Toroidal Ferrite Cores: GTR Series

G Ferrite Core – No nickel and competitively priced

  • High performance Nickel-Zinc ferrite cores for effective common mode EMI suppression.
  • Suitable for insertion on cables and wire bundles, in a single or multiple turns, before the final cable assembly.
  • Impedance performance ratio is proportional to the square of number of turns.
  • All toroids are supplied with de-burred edges to prevent damaging of cable insulation.
  • Toroids with epoxy coating are available upon request.
