Caution

■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. If store the chip monolithic ceramic capacitors in an atmosphere consisting of high temperature or humidity,

sulfur or chlorine gases, contaminants attach to the surface of external electrode, and bondability with

conductive glue may deteriorate. Do not store the capacitors in an atmosphere consisting of corrosive gas

(e.g., hydrogen sulfide, sulfur dioxide, chlorine, ammoria gas, etc.). Storage environment must be at room

temperature of +5°C to +40°C and a relative humidity of 20% to 70%, and use the product within six months

ꢀ after receipt.

In case of packaging, do not open the last wrappend, polyethylene bag, till just before using.

After unpacking, immediately reseal, or store in a desiccator containing a desiccant.

ꢀ

2. 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 bondability with conductive glue and

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

3. This product is chip monolithic ceramic capacitor limited to conductive glue mounting. Do not apply mounting method

other than conductive glue. Flow or reflow soldering can result in a lack of adhesive strength on the outer electrode by

poor wettability, which may result in chips breaking loose from the PCB.

■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.

Typical Voltage Applied to the DC capacitor

DC Voltage

DC Voltage+AC

AC Voltage

Pulse 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.

1-1. The capacitance of ceramic capacitors may change

sharply depending on the applied voltage. (See figure)

Please confirm the following in order to secure the

capacitance.

(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

constant circuit), please carefully consider the

voltage characteristics, and confirm the various

characteristics in the actual operating conditions

■Mounting

1. Selection of Conductive Adhesive, Mounting Process, and Bonding Strength

1.The acuired bonding strength may change greatly depending on the conductive adhesive to be used.

ꢀ Be sure to confirming the desired performance can be acquired in the assumed monting process

ꢀ with the conductive adhesive to be used.

2.Maintenance of the Mounting (pick and place) Machine

1. Make sure that the following excessive forces are not applied to the capacitors.

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) Adjust the nozzle pressure within a static load of 1N to 3N during mounting.

2.Dirt particles and dust accumulated between the suction nozzle and the cylinder inner wall prevent

the nozzle from moving smoothly. This imposes greater force upon the chip 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.

3.Moisture proof

1.To prevent the silver electrode migration, keep parts under low moisture condition with resin coating and the equivalent.

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

ꢀꢀby the kind of Coating material. Do not use strong acid type.

■ 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.

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, 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.
