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.

1-2. Influence of overvoltage
Overvoltage 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. Applied Voltage and Self-heating Temperature
1. When the capacitor is used in a high-frequency voltage, pulse voltage, application, be sure to take into account
self-heating may be caused by resistant factors of the capacitor.
1-1. The load should be contained to the level such that when measuring at atomospheric temperature of 25
℃
,
the product's self-heating remains below 20
℃
and surface temperature of the capacitor in the actual circuit
remains wiyhin the maximum operating temperature.
