EMI FERRITE
SLEEVE CORES ( RI Series )
 
- 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.
- All edges on the sleeve cores are de-burred to prevent damaging of the cable insulation.
- Economic solution to high impedance performance and efficient suppression of radiated emissions on power and signal/data and wiring systems.
