Power electronic capacitors (PEC) are components for equipment and installations which are operated at high power. They are used to convert and control this power. TDK produces the following kinds of power electronic capacitors: MKK DC/DCI (metallized plastic film, compact), PCC HP/LP (power capacitor chip high/low power), MKP (metallized plastic film, low-loss). All capacitors are self-healing, i.e. voltage breakdowns heal in a matter of microseconds and so produce no short circuit.
