Ferrite cores / Nanocrystalline Alloys cores etc.


Split type


Split type ferrite clamp, making it easy to fix on assembled wires.
Effective in suppressing common mode noise
Case has anti-slip means for cable ties.
Highly reliable since cable ties securely lock the clamp in addition to the casing lock. (Excluding RFC-20-A)
Operating temperature: –40 to +125℃.

  • Ferrite core (Noise filter)
  • Common mode noise suppression


Soft ferrite



Feature Split type, Plastic housing, With mounting fixture Cable types Round cable
Frequency band Signal noise Usage Heat resistance, For radiated noise
