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 which 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.

When DC-rated capacitors are to be used in input circuits

from a commercial power source (AC filter), be sure to

use Safety Certified Capacitors because various

regulations for withstanding voltage or impulses,

established for all equipment, should be taken into

consideration.

Continued on the following page.

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 voltage, pulse voltage, it may self-generate

heat due to dielectric loss.

Applied voltage should be the load such as self-

generated heat is within 20

°C on the condition of

atmosphere temperature 25

°C. When measuring, use a

thermocouple of small thermal capacity -K of ø0.1mm

in conditions where the capacitor is not affected by

radiant heat from other components or surrounding

ambient fluctuations. 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.)
