AC Filter Caps Get An Upgrade

TDK has updated its EPCOS B32754 to B32758 series ac filter capacitors to now cover a range of voltages from 250 to 400 Vac and offer capacitances of between 1 µF and 70 µF. The capacitors comply with IEC 61071: 2007 and are said to be extremely robust, even at high humidity, verified in a temperature, humidity, bias (THB) test at 60°C, 95% relative humidity, and an applied rated voltage for 1,344 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 27.7 mm, 37.5 mm, or 52.5 mm.

New VNA technologies enable mmWave broadband testing to 220 GHz, helping researchers and engineers to overcome test challenges and simplify mmWave testing.

Application development in the mmWave frequencies is growing. Broadband testing over hundreds of GHz of bandwidth is subject to repeatability/accuracy deficits, and engineers demand solutions to help overcome challenges and simplify mmWave testing.


The capacitors are suitable for demanding applications in industrial electronics such as output filtering for power supplies, frequency converters for drives and renewable energy, and/or UPS systems. For more details, visit TDK Corporation.
