EC-Series Capacitors

  • EC-Series Capacitors

    NWL’s EC-Series metalized polypropylene DC link film capacitors offer large capacitance values, high Joule energy, and large current ratings in a single welded metal package. This dry resin filled package can have a variety of low inductance terminal options, brackets for mounting, and can also incorporate additional metal structure to accommodate additional components such as resistors, chill plates, etc.

    EC-Series capacitors are well suited for many inverter applications including:

    • DC input / output filtering
    • DC Link
    • AC harmonic filtering
    • High energy storage pulse
    • Traction drives and heavy vehicles

    Unique features of the EC-Series capacitor include:

    • Large Capacitance values at high voltages – By utilizing fabricated welded metal packages, NWL can incorporate large capacitance values with the higher voltage ratings.
    • Rugged metal cases – Welded metal cans fabricated from alum, brass, steel, and stainless steel are provided for rugged packages up to 500 lbs.
    • Inverter design flexibility – With an already fabricated metal package, NWL can fasten onto the metal container unique brackets to accommodate a variety of functionality.
