SOLID SLEEVE
FERRITE CORES ( GRI/ RIB /BE 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.
RI/BE Series
Economic solution to high impedance performance and efficient
suppression of radiated emissions on power and signal/data
and wiring systems.
RIB Series
Small size ferrite beads
suitable for on-board EMI
suppression or insertion
on wire assemblies in limited
space applications.
