  • High current-handling capability
  • One- and three-phase design
    available
  • Suppression of asymmetrical
    interferences coupled in on lines. The high-frequency portions of the symmetrical data signal are decreased so far that EMC problems can be significantly reduced
  • Customized designs
  • UL 1446 Class 155 (F) Insulation system applicable

Standard common-mode chokes

  • Suppression of asymmetrical interference coupled in on lines. The high-frequency portions of the symmetrical data signal are decreased so far that EMC problems can be significantly reduced
  • Wide range of different core shapes and sizes available, with specific properties
  • High current-handling capability
  • High temperature stability
  • Standard and customized designs
  • UL and VDE certified



3-line filters

  • Mains filters for 3-phase applications with symmetrical load
  • Optimized leakage current
  • Book size or compact filters
  • B84243*****000 high attenuation
  • B84143D****R127 for very high attenation
