Film Capacitors: Series of Rugged AC Filter Capacitors Extended

TDK Corporation (TSE:6762) has extended its EPCOS B32754* to B32758* series of AC filter capacitors. They now cover a range of voltages from 250 V AC to 400 V AC and offer capacitances of between 1 µF and 70 µF. The capacitors comply with IEC 61071: 2007 and are extremely robust, even at high humidity. This has been verified in a temperature, humidity, bias (THB) test at 60 °C, 95 percent relative humidity and an applied rated voltage for 1344 hours, corresponding to 56 days, in according to IEC 60384 14:2013/AMD1:2016 Grade 3 Test A.

The capacitors are designed for a maximum operating temperature of 105 °C, and their epoxy resin-filled case conforms to UL 94 V-0. Depending on capacitance and rated voltage, the lead spacing is 27.5 mm, 37.5 mm, or 52.5 mm.

Thanks to their robustness, the capacitors are suitable for demanding applications in industrial electronics. These include, for example, output filtering for power supplies, frequency converters for drives and renewable energy, or UPS systems.
