AC Filter Capacitors / AC Power Film Capacitors :


Our AC Filter Capacitors and AC Power Electronics Capacitors are Plastic Enclosure and Dry construction design. For the advantage of these, please refer to Tech Consideration.

Typical Applications : 

  • Handling high RMS Current for high energy AC Filtering application
  • General purpose AC Application
  • Transient and Harmonic Damping
  • high power UPS and input / output filters
  • AC traction inverters
Advantages over metal can capacitors :

     o Plastic Capacitor Enclosure - safer

     o Dry Construction and no leaking fluids problem

     o Large capacitance in small package

     o High RMS Current handling capacity

     o Low ESR and Low Inductance

     o temperature range up to 105C

     o Flame Retardant

     o Longer Capacitor life
