APPLICATION NOTE AND LIMITING CONDITIONS
These capacitors are not suitable for mains applications as across-the-line capacitors without additional protection. These mains
applications are strictly regulated in safety standards and therefore electromagnetic interference suppression capacitors
conforming the standards must be used.
To select the capacitor for a certain application, the following conditions must be checked:
1. The peak voltage (U
2. The peak-to-peak ripple voltage (U
3. The voltage peak slope (dU/dt) shall not exceed the pulse slope at the DC voltage rating.
4. The maximum component surface temperature rise must be lower than 15 °C.
MAXIMUM REPETITIVE PEAK VOLTAGES
The capacitor unit may be subjected to the following surge without any significant reduction of lifetime expectancy
Document Number: 28164
Revision: 02-Feb-09
REPETITIVE SURGE VOLTAGE
1.1 x U
1.15 x U
1.2 x U
1.3 x U
1.5 x U
If the pulse voltage is lower than the rated DC voltage, the rated voltage pulse slope may be multiplied by U
by the applied voltage.
For all other pulses following equation must be fulfilled:
