EMI FERRITE
TOROIDAL CORES (TR Series )
 
- 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.
- Economical solution for suppressing common mode radiated emissions on power and signal/data cables and wiring systems.
