Solid Sleeve Ferrite Cores: GRI 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 round cables and wire bundles, in a single or multiple turns, before the final cable assembly. The sleeve cores can be permanently attached to cables by thermostatic resin molding or heat shrink tubing.
  • Design to help provide cost and time-to-market saving.
  • All edges on the sleeve cores are de-burred to prevent damaging of the cable insulation.
