3)
4)
5)
The capacitors must be stored in an ambient temperature of 5 to 40°C with a relative
humidity of 20 to 70%RH. The products should be used within 6 months upon
receipt.
The capacitors must be operated and stored in an environment free of dew
condensation and these gases such as Hydrogen Sulphide, Hydrogen Sulphate,
Chlorine, Ammonia and sulfur.
Avoid storing in sun light and falling of dew.
Do not use capacitors under high humidity and high and low atmospheric pressure
which may affect capacitors reliability.
Capacitors should be tested for the solderability when they are stored for long time.
1-2. Handling in transportation
In case of the transportation of the capacitors, the performance of the capacitors
may be deteriorated depending on the transportation condition.
(Refer to JEITA RCR-2335B 9.2 Handling in transportation)

Caution
2-1. Operating temperature
Operating temperature should be followed strictly within this specification, especially
be careful with maximum temperature.
1)
2)
3)
Do not use capacitors above the maximum allowable operating temperature.
Surface temperature including self heating should be below maximum operating
temperature.
(Due to dielectric loss, capacitors will heat itself when AC is applied. Especially at
high frequencies around its SRF, the heat might be so extreme that it may damage
itself or the product mounted on. Please design the circuit so that the maximum
temperature of the capacitors including the self heating to be below the maximum
allowable operating temperature. Temperature rise at capacitor surface shall be
below 20°C)
The electrical characteristics of the capacitors will vary depending on the
temperature. The capacitors should be selected and designed in taking the
temperature into consideration.
2-2. Operating voltage
1) Operating voltage across the terminals should be below the rated voltage.
When AC and DC are super imposed, V
0-P
must be below the rated voltage.
— (1) and (2)
C or pulse with overshooting, V
P-P
must be below the rated voltage.
— (3), (4) and (5)
When the voltage is started to apply to the circuit or it is stopped applying, the
irregular voltage may be generated for a transit period because of resonance or
switching. Be sure to use the capacitors within rated voltage containing these
Irregular voltage.
