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 :
1. The peak voltage (Vp) shall not be greater than the rated DC voltage (VRdc).
2. The peak-to-peak voltage (Vp-p) shall not be greater than the maximum Vp-p to avoid
the ionization 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 pulse slope may be multiplied by VRdc and divided by the applied voltage.
For all other pulses following equation must be fulfilled :
