NWL's ER Series DC Link capacitors offer a distinct alternative to small round cans, both film and electrolytic. Our tapered rectangular package enables the capacitor to be operated in a variety of orientations. One ER is equivalent to 3 or 4 round cans. Component inventory, integration, and installation are streamlined as a reult. Among the unique features of this capacitor are:

  • Unique stackable bracket design. Welded metal brackets enable capacitors to be mounted and stacked on floor or wall vertically or horizontally. Three bracket versions are available, as shown above.
  • Robust, rugged, and reliable construction. ER capacitors are used in numerous high relibility, mission-critical applications such as renewable energy inverters.
  • Inverter design flexibility. Compact design and mounting options give designs more component layout alternatives.
