High Energy Storage, Pulse Discharge

ER-Series Capacitors

Key Features

  • Capacitance: 10 to 4,100 uF
  • Voltage (DC): 400 to 6000 VDC
  • Voltage (AC): 10 to 660 VAC
  • Current (RMS): 5 to 200 amps
  • Current (Peak): 5 to 20,000 amp


ER-Series Capacitors

NWL’s ER-Series polypropylene DC link film capacitors offer a distinct alternative to small round cans, both film and electrolytic, with high capacitance density power in an economical standard package.

The rectangular aluminum package with various mounting bracket options enables the capacitor to be operated in a variety of orientations. Component inventory, integration, and installation are streamlined as a result.


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