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 may be affected by the storage conditions.
1-1. Store the capacitors in the following conditions:
Room Temperature of +5℃ to +40℃ and a Relative Humidity of 20% to 70%.
(1) High temperature and humidity conditions may accelerate the deterioration of mountability due to oxidation
of the terminal electrodes and deterioration of taping/packaging performance.
Therefore, maintain the appropriate storage temperature and humidity.
ꢀ
(2) Prolonged storage may cause oxidation of the electrodes and deterioration of the packaging materials.
If more than six months have elapsed since delivery, check the mounting before use.
Even if the storage period is short, do not exceed the specified atmospheric conditions.
(3) Store the capacitors in the original packaging without opening the smallest packing unit.
Do not exceed the above atmospheric conditions for any length of time.
1-2. Corrosive gas can react with the termination (external) electrodes or lead wires of capacitors, and result
in poor mountability. 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 mountability 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.

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.
<Applicable to Rated Voltage of less than 100VDC>
The load should be contained so that the self-heating
ꢀof the capacitor body remains below 20°C ,

3.Maintenance of the Mounting (pick and place) Machine
1. Make sure that the following excessive forces are not applied to the capacitors.
Check the mounting in the actual device under actual use conditions ahead of time.
1-1. In mounting the capacitors on the printed circuit board, any bending force against them shall be kept
to a minimum to prevent them from any damage or cracking. Please take into account the following precautions
and recommendations for use in your process.
(1) Adjust the lowest position of the pickup nozzle so as not to bend the printed circuit board.

2.Dirt particles and dust accumulated in the suction nozzle and suction mechanism prevent the nozzle from
moving smoothly. This creates excessive force on the capacitor during mounting, causing cracked chips.
Also, the locating claw, when worn out, imposes uneven forces on the chip when positioning, causing cracked chips.
The suction nozzle and the locating claw must be maintained, checked and replaced periodically.

4.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.
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.

! Caution
(1) Example of a suitable jig
[In the case of Single-side Mounting]
An outline of the board separation jig is shown as follows.
Recommended example: Stress on the component mounting position can be minimized by holding the
portion close to the jig, and bend in the direction towards the side where the capacitors are mounted.
Not recommended example: The risk of cracks occurring in the capacitors increases due to large stress
being applied to the component mounting position, if the portion away from the jig is held and bent in the
direction opposite the side where the capacitors are mounted.

[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.
6. 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.
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.

2. Others
2-1. In an Emergency
(1) If the equipment should generate smoke, fire, or smell, immediately turn off or unplug the equipment.
If the equipment is not turned off or unplugged, the hazards may be worsened by supplying continuous power.
(2) In this type of situation, do not allow face and hands to come in contact with the capacitor or burns may be caused
by the capacitor's high temperature.
2-2. Disposal of waste
When capacitors are disposed of, they must be burned or buried by an industrial waste vendor with the appropriate
licenses.
2-3. Circuit Design
(1) Addition of Fail Safe Function
Capacitors that are cracked by dropping or bending of the board may cause deterioration of the
insulation resistance, and result in a short. If the circuit being used may cause an electrical shock,
smoke or fire when a capacitor is shorted, be sure to install fail-safe functions, such as a fuse,
to prevent secondary accidents.
(2) This series are not safety standard certified products.

■ 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.
Moreover, when the mechanical vibration or shock is added to capacitor, noise may occur.

1.PCB Design
Relationshipbetweenloadandstrain
ε=
2Ewh2
When designing the board, keep in mind that
the amount of strain which occurs will increase
ꢀ depending on the sizeand material of the board.
ε：Strain on center of board (μst)
L：Distance between supporting points (mm)
P

L
When the load is constant, the following relationship can be established.
· As the distance between the supporting points (L) increases,the amount of strain also increases.
→Reduce the distance between the supporting points.
· As the elastic modulus (E) decreases, the amount of strain increases.
→Increase the elastic modulus.
·
As the board width (w) decreases, the amount of strain increases.
→Increase the width of the board.
As the board thickness (h) decreases, the amount of strain increases.
·
→Increase the thickness of the board.
Since the board thickness is squared, the effect on the amount of strain becomes even greater.
2.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
ꢀꢀby the kind of Coating material. Do not use strong acid type.

1.Transportation
1. The performance of a capacitor may be affected by the conditions during transportation.
1-1. The capacitors shall be protected against excessive temperature, humidity and mechanical force during transportation.
(1) Climatic condition
ꢀ･ low air temperature : -40℃
･ change of temperature air/air : -25℃/+25℃
･ low air pressure : 30 kPa
･ change of air pressure : 6 kPa/min.
(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.
