3-phase filter capacitors are robust

TDK CORP B3237* series of EPCOS MKD 3-phase capacitors for filter applications cover a voltage range from 250VRMS to 850 VRMSin 10 stages and are available with capacitances of between 3×10µF and 3×400µF. Depending on the type, devices are designed for currents of up to 60A. Internally, the capacitances are connected in three phases. In accordance with IEC 61071, the life expectancy is about 100,000 hours at the rated voltage, the maximum drop in capacitance being 3% from the initial value.
