OPERATING VOLTAGE

In case the voltage is applied to the circuit, starting as well as 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.

OPERATING TEMPERATURE AND SELF-GENERATED HEAT

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, pulse, or similar application,

it may have self-generated heat due to dielectric dissipation.

Temperature increase due to self-generated heating should not exceed 20 °C while operating at an atmosphere temperature of

25 °C.

When measuring, the surface temperature, make sure that the capacitor is not affected by radiant, conductive and convective

heat by its surroundings. Excessive heat may lead to thermo-mechanical deterioration of the capacitor's characteristics and

reliability.
