FT-3KM F series

FT-3KM F series is toroidal cores for common mode choke made of high permeability material FT-3M.

Their advantages compare to Mn-Zn ferrite cores are following:

  • 4 times higher impedance because of high impedance permeability
  • 4 times higher impedance with same dimensions
  • Requires less quantity to apply with same dimensions
  • Stable magnetic properties (core inductance and frequency dependance of impedance) against temperature change due to high curie temperature
