Series of rugged AC filter capacitors extended

TDK Corporation has expanded its EPCOS B32754* to B32758* series of AC filter capacitors. They now comprise a range of voltages from 250VAC to 400VAC and provide capacitances of between 1µF and 70µF. The capacitors comply with IEC 61071: 2007 and are remarkably robust, even at high humidity. This has been confirmed in a THB test at 60C, 95% 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 intended for a maximum operating temperature of 105C, and their epoxy resin-filled case conforms to UL 94V-0. Depending on capacitance and rated voltage, the lead spacing is 27.5mm, 37.5mm, or 52.5mm. Due to their robustness, the capacitors are ideal for demanding applications in industrial electronics including output filtering for power supplies, frequency converters for drives and renewable energy, or UPS systems.
