Metallized Polypropylene Film Capacitors
DC Capacitor MKP Type
MEASURING THE COMPONENT TEMPERATURE
Thermocouple
The case temperature is measured in unloaded (Tamb) and maximum loaded condition (TC).
To avoid thermal radiation or convection, the capacitor must be tested in a closed area from air circulation.
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:
• The continuous peak voltage (UP+) shall not exceed the rated DC voltage rating (UNDC)
• The peak-to-peak ripple voltage (UPP) shall not be greater than 0.2 x (UNDC)

• 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: dc-film@vishay.com
• The voltage peak slope (dU/dt) shall not exceed the pulse slope at the DC voltage rating.
If the pulse voltage is lower than the rated DC voltage, the rated voltage pulse slope may be multiplied by UNDC and divided
by the applied voltage.
For all other pulses following equation must be fulfilled:
