● Temperature Characteristics
● Characteristics of Voltage-Frequency
Rated Voltage 3 kVDC
The graphs above show the maximum permissable voltage
when using a capacitor with an AC sine wave voltage.
When measuring this voltage in room temperature (25 °C), the
capacitor self-heat generation will rise a maximum of 20 °C.
When using a pulse voltage or an AC voltage other than a sine
wave, confi rm that the capacitor self-heat generation is less
than 20 °C in an ambient room temperature of 25 °C.
The self-heat generation temperature is the difference be tween
the surface temperature and the ambient room tem perature.
As for the situation when the self-heat generation temperature is
more than 25 °C, refer to the fi gure on the right.
