E-Series Polypropylene DC-link Film Capacitors

CDE’s E-Series polypropylene DC-link film capacitors offer an alternative to small round cans, both film and electrolytic, with high capacitance density in an economical standard dry resin-filled package. The rectangular painted aluminum package with various termination options allows for versatility in design layout.

E-Series capacitors are well suited for many inverter and power supply applications including:

  • DC input / output filtering
  • DC Link
  • AC harmonic filtering
  • High energy storage pulse

Unique features of the E-Series capacitor include:

  • Standard economic package – With standard case construction and end cap covers, CDE created automated assembly to enhance production efficiency.
  • Terminal options – Threaded terminals, threaded inserts, insulated exiting wires, and laminated bus are only a few of the terminal options to select from.
  • Inverter design flexibility – Compact standard rectangle case, and central mounting stud option give designs various component layout alternatives.
  • E-Series Capacitors Product Information and Specifications

    Originally designed as an alternative to electrolytic type capacitors, E-Series capacitors are now widely used for DC link, AC harmonic filter, energy storage, and pulse power applications. They provide a unique rectangular can approach utilizing the latest polypropylene film dielectric technologies of self-healing electrodes and use UL 94V-0 thermosetting dry resin encapsulation.
