Cores for Low Frequency Noise: TRM Series

“Mn” ferrite cores, suitable solutions for conductive and radiation noise in low frequency range

  • High Impedance noise filter for low frequency (kHz to MHz) range
  • Turning the cable around the core increases effectiveness by a power of 2 (N²)
  • Epoxy coated ferrite core has rounded corners to reduce the load on cable
  • Operating temperature -40 ~ 85 °C
