Our Selling Points : 
Tailor-Made Design Capacitors

We can make power film capacitor according to your application need.
Most of the Electrical Characteristic, Mechanical size and Construction, Electrical Connection can be tailor-made.
Our engineers can design various types of film foil capacitors to suit for various applications. Their jobs not only concentrate on the capacitor electrical characteristic performance but also mechanical need. Different electrical connections and capacitor  installation options can be supported so as to increase your design flexibility. Please refer to our Capacitor configurations page.

Most of our Power Film Capacitors can meet high RMS Current, high Voltage and high dv/dt requirement even at 105C.

Capacitor Construction and mounting

  • Plastic Capacitor Enclosure : high insulation resistance, less chance for electric shock when compare with traditional aluminum enclosure capacitor. It is safer. This is important  especially for capacitor maintenance and replacement on site.
  • Dry construction : doesn't have impregnant liquid leakage problem
  • All Epoxy Resin and Plastic materials are self-extinguishing UL94-V0 grade
  • Optional : Thermoplastic Plastic Capacitor Enclosure - so that our capacitor can be operated at a higher temperature range and harsh working environment. We can support capacitor temperature up to 105C. For more details, please feel free to contact us.
  • For capacitor packaging and configuration, we have many choice suit for customer application.
  • smaller capacitor size and light weight

Capacitor with Thermal Sensor Options

  • Thermocouple can be integrated into the capacitor body.
  • Output temperature signal can be used as one of the reference signals in the circuit and trigger other function

Electrical Characteristics

  • can be worked under medium frequency range
  • Low ESR when compare with traditional paper capacitor and oil impregnated capacitor
  • low ESL
  • higher temperature range : support -20C to +85C / -40C to +105C Capacitor
  • Capacitance, Voltage, Testing Voltage, ESR, Size, Discharge Current Capacity, Operating Temperature, Operating Lifetime and Electrical Connection can be  designed according customer's application need

Electrical Connections

  • different Electrical connections and capacitor Mounting options available, that increase your design flexibility.
  • Terminations : solder tags, single or double quick terminal, Stiff wire, Flexible wire, Twin-core cable and Tin-coated copper lead, Screws and Nuts
  • Stiff wire, Flexible wire : UL #1015,105¢J, AWG#16, 18, 20
  • Wire and Cable with receptacle, terminal or even power connectors
  • Terminal type : Ring, Y or Pin terminal with various size
  • M4 M5 M6 M8, M10 Screw Threads and Nuts
