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. The performance of chip monolithic 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) Sunlight, dust, rapid temperature changes, corrosive gas atmosphere, or high temperature and humidity
conditions during storage may affect solderability and packaging performance.
Therefore, please maintain the storage temperature and humidity. Use the product within six months after receipt ,
as prolonged storage may cause oxidation of the terminations (outer electrodes).
(2) Please confirm solderability before using after six months.
Store the capacitors without opening the original bag.
Even if the storage period is short, do not exceed the specified atmospheric conditions.
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.
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.
<Applicable to Rated Voltage of less than 100VDC>
1-1. The load should be contained to the level
such that when measuring at atmospheric
temperature of 25°C, the product's self-heating
remains below 20°C and the surface
temperature of the capacitor in the actual circuit
remains within the maximum operating
temperature.
