Solid Sleeve Ferrite Cores: GRI Series

G-core series ferrites – Nickel-free and competitively priced

High performance Magnesium-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 final cable assembly
Can be permanently attached to cables by thermostatic resin molding or heat shrink tubing
Design to help provide cost and time-to-market savings
All edges on the sleeve cores are de-burred
