AC Filtering Capacitors

AC Filtering Capacitors
Qiyutech specializes in designing and customizing AC filter capacitors with different capacitances. These AC capacitors have lower ESR, high ipeak score, high life expectancy, low self-inductance, -40 ~ +85/105℃ temperature range, and 5~200μF capacitance range. Strict quality checking guaranteed!
  • Applications
  • Technical data & Specification
  • Outline drawings


  • Input/output side of the filter of Solar energy / wind power inverter.

  • Input/output side filter of inverter power supply, UPS power supply, high-power switching power supply.

  • The ac filter of electronic equipment such as high-power inverter.




These heavy-duty, yet small size AC filter capacitors are broadly used in power electronics. They deliver excellent performance with low self-inductance, high IRMS, and Ipeak rating. Except for high life expectancy and reliability, these AC capacitors feature; 5~200μF Capacitance, non-inductive construction, and metalized self-healing polypropylene film elements. The elements are encapsulated in alumium casing and sealed with UL94 -V0 flame retardant resin for super-solid structure and to control AC ionization. Moreover, these capacitors reach to the maximum dielectric power in -40~+85/105℃ temperature.

Side by side pre-listed capacitors, we are specialized in customizing capacitors, terminal styles, and alumium cases according to your requirements. And all capacitors of Qiyutech are RoHS compliant.


Description of Products

  • Reference standard: IEC 61071.

  • Metallized polypropylene film wound, non-inductive construction.

  • UL94 -V0 flame retardant resin encapsulation, solid-state structure.

  • Special metallized coating can effectively control the ac ionization, long life, stability of capacitance.

  • To adopt technology patent with self-owned intellectual property right approved by our country to manufacture products.

  • Very low ESR, withstanding very high effective value of current Irms and peak to peak value of current Ipp.

  • Withstanding higher non-periodic peak to peak voltage Us.

  • Especially used in filtering high frequency carrier wave and harmonic wave on the output side of wind power, photovoltaic inverter, high-power UPS and so on.


Technology Features

  • To adopt standardizing internal custom-made, structure member assuring internal connection reliable, lower ESR, terminals can endure more torque force.

  • Using special mould in process of manufacturing product, assuring accuracy of dimensions of product’s terminals and successful in first mounting them when many products are used to connect together in parallel.
