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.
For capacitors connected in parallel, normally the proof voltage and possibly the rated voltage must be reduced. For information
depending of the capacitance value and the number of parallel connections contact:
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

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 V
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
