TDK Corporation today announced a new series of EPCOS MKP AC capacitors for filter applications. The B33331V* series capacitors are designed for a rated voltage of 460 VRMS, corresponding to a peak voltage of 650 V, and cover a capacitance range from 2 µF to 50 µF. Both the cans and the tops are constructed of aluminum, making the overall design particularly robust. Despite this, the dimensions – depending on the type – range from just 30 mm x 55 mm to 50 mm x 100 mm (D x H).
The reliability of the new capacitors, even under harsh conditions, has been verified by a temperature, humidity, bias (THB) test at 85 °C, 85 percent relative humidity and an applied rated voltage for 1000 hours. In compliance with IEC 61071, the life expectancy is at least 100,000 hours. 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.
Among other applications, the new capacitors can be used as output filters of photovoltaic inverters, frequency converters and uninterruptible power supplies.
