Cable Snap-Its

Fair-Rite Cable Snap-Its easily accommodate round cables or bundled wires from 2.5mm to 25.4mm. These Snap-Its are available in four ferrite material classes to suppress differential or common-mode conducted EMI from 1Mhz into the GHz region. Fair-Rite Cable Snap-Its feature polypropylene cases that meet the RoHS restrictions of hazardous substances and have a flammability rat5ing of UL94 V-0. Fair-Rite cores are tested with the shortest practical wire length.
