TDK EPCOS MKP B33331V* series AC capacitors for filter applications

TDK Corporation has available the latest series of EPCOS MKP AC capacitors for filter applications. The components of the B33331V* series are designed for a rated voltage of 460 V_rms, corresponding to a peak voltage of 650 V, and cover a capacitance range from 2 to 50 µF. Both the cans and the tops are constructed of aluminium, making the overall design particularly robust. Despite this, the dimensions — depending on the type — range from 30 x 55 mm to 50 x 100 mm.

The reliability of the capacitors, even under harsh conditions, has been verified by a temperature, humidity, bias (THB) test at 85°C, 85% relative humidity and an applied rated voltage for 1000 h. In compliance with IEC 61071, the life expectancy is at least 100,000 h. The capacitors bear the CE symbol, types with a can diameter of >40 mm are UL approved and the insulation of the connections conforms to UL 94 V0. In the event of excessive pressure in the capacitor case due to an overload, the integrated overpressure disconnection safety device isolates both terminals from the winding.

The capacitors can be used as output filters of photovoltaic inverters, frequency converters and uninterruptible power supplies, as well as for general filtering applications.
