AC Filter Capacitors

AC filter capacitors, this series of products has covered the voltage range from 250VAC to 400VAC, and the capacitance range is from 1µF to 70µF. The capacitor elements comply with the IEC 61071:2007 standard and are extremely robust and operate reliably even in high humidity environments. And the component characteristics have met the THB test verification under the condition of IEC 60384-14:2013/AMD1:2016 Class 3 A test standard, that is, the temperature is 60°C, the humidity is 95%, and the working voltage is rated voltage. Under normal conditions, it runs for 1366 hours (56 days).

The capacitors are designed for a maximum ambient operating voltage of 105°C and feature an epoxy-filled case with a UL 94 V-0 flammability rating. Due to their robustness, the capacitors are ideal for demanding industrial electronics applications, including output filtering of power supplies, frequency converters for drives and renewable energy sources, or uninterruptible power supply (UPS) systems etc.
