Capacitor Schematic


  • Input filter, DC link and DC bus capacitorsInput Filters
  • DC Link
  • DC Bus

These applications require continuous DC voltages and/or additional rms currents created by AC voltage waveforms imposed on the DC voltage.


  • NWL capacitors for snubber, commutation and clamping applicationsSnubbers
  • Commutation
  • Clamping

These applications  require low inductance capacitors to protect IGBT or high power switches from voltage transients.  These products are able to manage high peak currents, short pulse widths, and high frequencies creating elevated rms currents.


  • pulse discharge, energy storage, and surge protection capacitorsPulse Discharge
  • Energy Storage
  • Surge Protection

These applications require high energy storage, short peak voltages, and an ability to discharge in narrow pulse widths.


  • AC voltage, harmonic filtering and commutation capacitorsAC Voltage
  • Harmonic Filtering
  • Commutation

These applications utilize a full AC voltage waveform.  Continuous sine wave, square wave, saw tooth, or other are accommodated with these products.
