APPLICATION NOTE AND LIMITING CONDITIONS

These capacitors are not suitable for mains application as across-the-line capacitors without additional

protection.

To select the capacitor for a certain application, the following conditions must be checked :

inception level.

3. The voltage pulse slope (dV/dt) shall not exceed the rated voltage pulse slope in an RC-circuit at rated

voltage and without ringing. If the pulse voltage is lower than the rated DC voltage, the rated voltage

For all other pulses following equation must be fulfilled :
