1. Operating Voltage

When DC-rated capacitors are to be used in AC or ripple

current circuits, be sure to maintain the Vp-p value of the

applied voltage or the Vo-p that contains DC bias within

the rated voltage range.

When the voltage is applied to the circuit, starting or

stopping may generate irregular voltage for a transit

period because of resonance or switching. Be sure to use

a capacitor with a rated voltage range that includes

these irregular voltages.

2. Operating Temperature and Self-generated Heat

(Apply to B/E/F Char.)

Keep the surface temperature of a capacitor below the

upper limit of its rated operating temperature range. Be

sure to take into account the heat generated by the

capacitor itself. When the capacitor is used in a high-

frequency current, pulse current or similar current, it may

have self-generated heat due to dielectric loss. Applied

voltage load should be such that self-generated heat is

within 20°C under the condition where the capacitor is

subjected to an atmospheric temperature of 25°C. When

measuring, use a thermocouple of small thermal

capacity-K of ø0.1mm under conditions where the

capacitor is not affected by radiant heat from other

components or wind from surroundings. Excessive heat

may lead to deterioration of the capacitor's

characteristics and reliability. (Never attempt to perform

measurement with the cooling fan running. Otherwise,

accurate measurement cannot be ensured.)

3. Test Condition for Withstanding Voltage

(1) Test Equipment

Test equipment for AC withstanding voltage should be

used with the performance of the wave similar to

50/60Hz sine wave.

If the distorted sine wave or overload exceeding the

specified voltage value is applied, a defect may be

caused.
