■Limitation of Applications

Please contact us before using our products for the applications listed below which require especially high reliability

ꢀ for the prevention of defects which might directly cause damage to the third party's life, body or property.

ꢀꢀꢀ①Aircraft equipment ②Aerospace equipment ③Undersea equipment ④Power plant control equipment

ꢀꢀꢀ⑤Medical equipment ⑥Transportation equipment(vehicles,trains,ships,etc.) ⑦Traffic signal equipment

ꢀꢀꢀ⑧Disaster prevention / crime prevention equipment

⑨Data-processing equipment

ꢀꢀꢀ⑩Application of similar complexity and/or reliability requirements to the applications listed in the above.

■Storage and Operation condition

1. The performance of chip multilayer ceramic capacitors (henceforth just "capacitors") may be affected by the

storage conditions. Please use them promptly after delivery.

1-1. Maintain appropriate storage for the capacitors using the following conditions:

Room Temperature of +5℃ to +40℃ and a Relative Humidity of 20% to 70%.

High temperature and humidity conditions and/or prolonged storage may cause deterioration of the packaging

materials. If more than six months have elapsed since delivery, check packaging, mounting, etc. before use.

In addition, this may cause oxidation of the electrodes. If more than one year has elapsed since delivery,

also check the solderability before use.

ꢀ

1-2. Corrosive gas can react with the termination (external) electrodes or lead wires of capacitors, and result

in poor solderability. Do not store the capacitors in an atmosphere consisting of corrosive gas (e.g.,hydrogen

sulfide, sulfur dioxide, chlorine, ammonia gas etc.).

1-3. Due to moisture condensation caused by rapid humidity changes, or the photochemical change caused

by direct sunlight on the terminal electrodes and/or the resin/epoxy coatings, the solderability and

electrical performance may deteriorate. Do not store capacitors under direct sunlight or in high huimidity

conditions

■Rating

1.Temperature Dependent Characteristics

1. The electrical characteristics of the capacitor can change with temperature.

1-1. For capacitors having larger temperature dependency, the capacitance may change with temperature

changes. The following actions are recommended in order to ensure suitable capacitance values.

(1) Select a suitable capacitance for the operating temperature range.

(2) The capacitance may change within the rated temperature.

When you use a high dielectric constant type capacitor in a circuit that needs a tight (narrow) capacitance

tolerance (e.g., a time-constant circuit), please carefully consider the temperature characteristics, and

carefully confirm the various characteristics in actual use conditions and the actual system.

2.Measurement of Capacitance

1. Measure capacitance with the voltage and frequency specified in the product specifications.

1-1. The output voltage of the measuring equipment may decrease occasionally when capacitance is high.

Please confirm whether a prescribed measured voltage is impressed to the capacitor.

1-2. The capacitance values of high dielectric constant type capacitors change depending on the AC voltage applied.

Please consider the AC voltage characteristics when selecting a capacitor to be used in a AC circuit.

3.Applied Voltage

1. Do not apply a voltage to the capacitor that exceeds the rated voltage as called out in the specifications.

1-1. Applied voltage between the terminals of a capacitor shall be less than or equal to the rated voltage.

(1) When AC voltage is superimposed on DC voltage, the zero-to-peak voltage shall not exceed the rated DC voltage.

When AC voltage or pulse voltage is applied, the peak-to-peak voltage shall not exceed the rated DC voltage.

(2) Abnormal voltages (surge voltage, static electricity, pulse voltage, etc.) shall not exceed the rated DC voltage.

(E：Maximum possible applied voltage.)

1-2. Influence of over voltage

Over voltage that is applied to the capacitor may result in an electrical short circuit caused by the breakdown

of the internal dielectric layers .

The time duration until breakdown depends on the applied voltage and the ambient temperature.

4.Type of Applied Voltage and Self-heating Temperature

1.Confirm the operating conditions to make sure that no large current is flowing into the capacitor due to the

continuous application of an AC voltage or pulse voltage.

When a DC rated voltage product is used in an AC voltage circuit or a pulse voltage circuit, the AC current

or pulse current will flow into the capacitor; therefore check the self-heating condition.

Please confirm the surface temperature of the capacitor so that the temperature remains within the upper limits

of the operating temperature, including the rise in temperature due to self-heating. When the capacitor is

used with a high-frequency voltage or pulse voltage, heat may be generated by dielectric loss.

[Example of Temperature Rise (Heat Generation) in Chip

Sample: R(R1) characteristics 10μF, Rated voltage: DC10V

The load should be contained so that the self-heating

(1) Determine whether the capacitance change caused

by the applied voltage is within the allowed range .

(2) In the DC voltage characteristics, the rate of

capacitance change becomes larger as voltage

increases, even if the applied voltage is below

the rated voltage. When a high dielectric constant

type capacitor is used in a circuit that requires a

tight (narrow) capacitance tolerance (e.g., a time

3. When a capacitor is mounted at a temperature lower than the peak reflow temperature recommended by the

solder manufacturer, the following quality problems can occur. Consider factors such as the placement of

peripheral components and the reflow temperature setting to prevent the capacitor’s reflow temperature from

dropping below the peak temperature specified. Be sure to evaluate the mounting situation beforehand and

verify that none of the following problems occur.

･Drop in solder wettability

･Solder voids

･Possible occurrence of whiskering

･Drop in bonding strength

･Drop in self-alignment properties

･Possible occurrence of tombstones and/or shifting on the land patterns of the circuit board

4. Optimum Solder Amount for Reflow Soldering

4-1. Overly thick application of solder paste results in a excessive solder fillet height.

This makes the chip more susceptible to mechanical and thermal stress on the board and may cause the chips to crack.

4-2. Too little solder paste results in a lack of adhesive strength on the termination, which may result in chips breaking

loose from the PCB.

4-3. Please confirm that solder has been applied smoothly to the termination.

^!Caution

4-2.Flow Soldering

1. This product is not apply flow soldering.

4-3.Correction of Soldered Portion

When sudden heat is applied to the capacitor, distortion caused by the large temperature difference occurs internally,

and can be the cause of cracks. Capacitors also tend to be affected by mechanical and thermal stress depending

on the board preheating temperature or the soldering fillet shape, and can be the cause of cracks.

Please refer to "1. PCB Design" or "3. Optimum solder amount" for the solder amount and the fillet shapes.

1. Correction with a Soldering Iron

1-1. In order to reduce damage to the capacitor, be sure to preheat the capacitor and the mounting board.

Preheat to the temperature range shown in Table 3. A hot plate, hot air type preheater, etc. can be used for preheating.

1-2. After soldering, do not allow the component/PCB to cool down rapidly.

1-3. Perform the corrections with a soldering iron as quickly as possible. If the soldering iron is applied too long,

there is a possibility of causing solder leaching on the terminal electrodes, which will cause deterioration of the

adhesive strength and other problems.

2. Correction with Spot Heater

Compared to local heating with a soldering iron, hot air heating by a spot heater heats the overall component

and board, therefore, it tends to lessen the thermal shock. In the case of a high density mounted board,

a spot heater can also prevent concerns of the soldering iron making direct contact with the component.

2-1. If the distance from the hot air outlet of the spot heater to the component is too close, cracks may occur due to

thermal shock. To prevent this problem, follow the conditions shown in Table 4.

2-2. In order to create an appropriate solder fillet shape, it is recommended that hot air be applied at the angle shown

in Figure 1.

or broken solder joints. Before starting your production process, test your cleaning equipment / process to insure

it does not degrade the capacitors.

6.Electrical Test on Printed Circuit Board

1. Confirm position of the support pin or specific jig, when inspecting the electrical performance of a

capacitor after mounting on the printed circuit board.

1-1. Avoid bending the printed circuit board by the pressure of a test-probe, etc.

The thrusting force of the test probe can flex the PCB, resulting in cracked chips or open solder

joints. Provide support pins on the back side of the PCB to prevent warping or flexing.

Install support pins as close to the test-probe as possible.

1-2. Avoid vibration of the board by shock when a test -probe contacts a printed circuit board.

[In the case of Double-sided Mounting]

Since components are mounted on both sides of the board, the risk of cracks occurring can not be avoided with the

above method. Therefore, implement the following measures to prevent stress from being applied to the components.

ꢀ (Measures)

(1) Consider introducing a router type separator.

ꢀ

ꢀIf it is difficult to introduce a router type separator, implement the following measures.

(Refer to item 1. Mounting Position)

(2) Mount the components parallel to the board separation surface.

(3) When mounting components near the board separation point, add slits in the separation position

near the component.

(4) Keep the mounting position of the components away from the board separation point.

(2) Example of a Disc Separator

An outline of a disc separator is shown as follows. As shown in the Principle of Operation, the top

blade and bottom blade are aligned with the V-grooves on the printed circuit board to separate the board.

In the following case, board deflection stress will be applied and cause cracks in the capacitors.

(1) When the adjustment of the top and bottom blades are misaligned, such as deviating in the top-bottom,

left-right or front-rear directions

(2) The angle of the V groove is too low, depth of the V groove is too shallow, or the V groove is misaligned

top-bottom

IF V groove is too deep, it is possible to brake when you handle and carry it. Carefully design depth of the

V groove with consideration about strength of material of the printed circuit board.

Caution

(3) Example of Router Type Separator

[ Outline Drawing ]

Router

The router type separator performs cutting by a router

rotating at a high speed. Since the board does not

bend in the cutting process, stress on the board can

be suppressed during board separation.

When attaching or removing boards to/from the router type

separator, carefully handle the boards to prevent bending.

8. Assembly

1. Handling

If a board mounted with capacitors is held with one hand, the board may bend.

Firmly hold the edges of the board with both hands when handling.

If a board mounted with capacitors is dropped, cracks may occur in the capacitors.

Do not use dropped boards, as there is a possibility that the quality of the capacitors may be impaired.

2. Attachment of Other Components

2-1. Mounting of Other Components

Pay attention to the following items, when mounting other components on the back side of the board after

capacitors have been mounted on the opposite side.

When the bottom dead point of the suction nozzle is set too low, board deflection stress may be applied

to the capacitors on the back side (bottom side), and cracks may occur in the capacitors.

· After the board is straightened, set the bottom dead point of the nozzle on the upper surface of the board.

· Periodically check and adjust the bottom dead point.

Suction Nozzle

2-2. Inserting Components with Leads into Boards

When inserting components (transformers, IC, etc.) into boards, bending the board may cause cracks in the

capacitors or cracks in the solder. Pay attention to the following.

· Increase the size of the holes to insert the leads, to reduce the stress on the board during insertion.

· Fix the board with support pins or a dedicated jig before insertion.

· Support below the board so that the board does not bend. When using support pins on the board,

periodically confirm that there is no difference in the height of each support pin.

Component with Leads

2-3. Attaching/Removing Sockets and/or Connectors

Insertion and removal of sockets and connectors, etc., might cause the board to bend.

Please insure that the board does not warp during insertion and removal of sockets and connectors, etc.,

ꢀꢀ ꢀor the bending may damage mounted components on the board.

Socket

2-4. Tightening Screws

The board may be bent, when tightening screws, etc. during the attachment of the board to a shield or

chassis. Pay attention to the following items before performing the work.

· Plan the work to prevent the board from bending.

· Use a torque screwdriver, to prevent over-tightening of the screws.

· The board may bend after mounting by reflow soldering, etc. Please note, as stress may be applied

to the chips by forcibly flattening the board when tightening the screws.

■ Rating

1.Operating Temperature

1. The operating temperature limit depends on the capacitor.

1-1. Do not apply temperatures exceeding the maximum operating temperature.

It is necessary to select a capacitor with a suitable rated temperature that will cover the operating temperature range.

It is also necessary to consider the temperature distribution in equipment and the seasonal temperature variable

factor.

1-2. Consider the self-heating factor of the capacitor

The surface temperature of the capacitor shall not exceed the maximum operating temperature including self-heating.

2.Atmosphere Surroundings (gaseous and liquid)

1. Restriction on the operating environment of capacitors.

1-1. Capacitors, when used in the above, unsuitable, operating environments may deteriorate due to the corrosion

of the terminations and the penetration of moisture into the capacitor.

1-2. The same phenomenon as the above may occur when the electrodes or terminals of the capacitor are subject

to moisture condensation.

1-3. The deterioration of characteristics and insulation resistance due to the oxidization or corrosion of terminal

ꢀꢀelectrodes may result in breakdown when the capacitor is exposed to corrosive or volatile gases or solvents

for long periods of time.

3.Piezo-electric Phenomenon

1. When using high dielectric constant type capacitors in AC or pulse circuits, the capacitor itself vibrates

at specific frequencies and noise may be generated.

■Soldering and Mounting

1.PCB Design

1. Notice for Pattern Forms

1-1. Unlike leaded components, chip components are susceptible to flexing stresses since they are mounted

directly on the substrate.

They are also more sensitive to mechanical and thermal stresses than leaded components.

Excess solder fillet height can multiply these stresses and cause chip cracking.

When designing substrates, take land patterns and dimensions into consideration to eliminate the possibility

of excess solder fillet height.

1-2. There is a possibility of chip cracking caused by PCB expansion/contraction with heat, because stress

on a chip is different depending on PCB material and structure.When the thermal expansion coefficient

greatly differs between the board used for mounting and the chip,it will cause cracking of the chip due to

the thermal expansion and contraction. When capacitors are mounted on a fluorine resin printed circuit

board or on a single-layered glass epoxy board, it may also cause cracking of the chip for the same reason.

Notice

2.Reflow soldering

The flux in the solder paste contains halogen-based substances and organic acids as activators.

ꢀ Strong acidic flux can corrode the capacitor and degrade its performance.

Please check the quality of capacitor after mounting.

3.Washing

1. Please evaluate the capacitor using actual cleaning equipment and conditions to confirm the quality,

and select the solvent for cleaning.

2. Unsuitable cleaning may leave residual flux or other foreign substances, causing deterioration of

electrical characteristics and the reliability of the capacitors.

4.Coating

1. A crack may be caused in the capacitor due to the stress of the thermal contraction of the resin during curing process.

The stress is affected by the amount of resin and curing contraction. Select a resin with low curing contraction.

The difference in the thermal expansion coefficient between a coating resin or a molding resin and the capacitor

may cause the destruction and deterioration of the capacitor such as a crack or peeling, and lead to the deterioration

of insulation resistance or dielectric breakdown.

Select a resin for which the thermal expansion coefficient is as close to that of the capacitor as possible.

A silicone resin can be used as an under-coating to buffer against the stress.

2. Select a resin that is less hygroscopic.

Using hygroscopic resins under high humidity conditions may cause the deterioration of the insulation resistance

of a capacitor. An epoxy resin can be used as a less hygroscopic resin.

3．The halogen system substance and organic acid are included in coating material, and a chip corrodes

(2) Mechanical condition

Transportation shall be done in such a way that the boxes are not deformed and forces are not directly passed

on to the inner packaging.

1-2. Do not apply excessive vibration, shock, or pressure to the capacitor.

(1) When excessive mechanical shock or pressure is applied to a capacitor, chipping or cracking may occur

in the ceramic body of the capacitor.

(2) When the sharp edge of an air driver, a soldering iron, tweezers, a chassis, etc. impacts strongly on the surface

of the capacitor, the capacitor may crack and short-circuit.

1-3. Do not use a capacitor to which excessive shock was applied by dropping etc.

A capacitor dropped accidentally during processing may be damaged.

2.Characteristics Evaluation in the Actual System

1. Evaluate the capacitor in the actual system,to confirm that there is no problem with the performance and specification

values in a finished product before using.

2. Since a voltage dependency and temperature dependency exists in the capacitance of high dielectric type ceramic

capacitors, the capacitance may change depending on the operating conditions in the actual system.

Therefore,be sure to evaluate the various characteristics, such as the leakage current and noise absorptivity,

which will affect the capacitance value of the capacitor.

3. In addition,voltages exceeding the predetermined surge may be applied to the capacitor by the inductance in

the actual system. Evaluate the surge resistance in the actual system as required.
