Ni-Zn Ferrite Clamp: KRFC Series

Split-core ferrite clamp designed to filter noise from around 3 ∼ 50 MHz

  • Effective suppression of conducted noise up to 30MHz and radiated noise over 30MHz
  • Cable tie loop can assist to fix ferrite clamp to wire harness (except for KRFC-4 )
  • Notches on both sides of the inner side of the plastic clamp prevent wires from shifting out of place when winding ( Photo A)
  • Operating temperature: -20 ~ 85°C
  • With optional mounting fixture, the product can be assembled on enclosure by M4 screw. (KRFCK2-15, KRFCK2-26)
  • Operating temperature: -40°C ~ +85°C
