  • usable for basic and reinforced equipment
  • Quasi linear saturation for storage mode
  • 40 to 450 microjoules storage
  • Resonance Frequency from 500kHz to 60MHz in symmetrical mdoe
  • Custom-specific versions are available on request
  • Multiple housing options

Typical applications

  • Energy filtering
  • Multistage discrete filtering
  • General purpose differential/symmetrical mode filtering
  • SMPS and UPS
