Ac filter capacitors are compact, robust

Electronics Supply Chain capacitors capacitors

TDK EPCOS B33331V series of MKP AC capacitors for filter applications are designed for a rated voltage of 460 VRMS, corresponding to a peak voltage of 650V and cover a capacitance range from 2µF to 50µF. 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 30mm x 55mm to 50mm x 100mm (D x H). Device’s reliability, 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-hours. In compliance with IEC 61071, the life expectancy is at least 100,000-hours.
