APPLICATION NOTE AND LIMITING CONDITIONS
These capacitors are not suitable for mains applications as across-the-line capacitors without additional protection, as described
hereunder. 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 voltage (U
3. The voltage peak slope (dU/dt) shall not exceed the rated voltage pulse slope in an RC-circuit at rated voltage and without
4. The maximum component surface temperature rise must be lower than the limits (see graph max. allowed component
5. Since in circuits used at voltages over 280 V peak-to-peak the risk for an intrinsically active flammability after a capacitor
6. When using these capacitors as across-the-line capacitor in the input filter for mains applications or as series connected with
Voltage Conditions for 6 Above
EXAMPLE
C = 330 nF - 63 V used for the voltage signal shown in next drawing.
U
The ambient temperature is 35 °C
Checking conditions:
1. The peak voltage U
2. The peak-to-peak voltage 40 V is lower than 2√2 x 40 Vac = 113 U
3. The voltage pulse slope (dU/dt) = 40 V/100 µs = 0.4 V/µs
4. The dissipated power is 16.2 mW as calculated with fourier terms
5. Not applicable

ringing. If the pulse voltage is lower than the rated DC voltage, the rated voltage pulse slope may be multiplied by U
divided by the applied voltage.
For all other pulses following equation must be fulfilled:
