75 CORE FOR COMMON MODE CHOKES
Explanation of Part Numbers:
– Digits 1 & 2 = Product Class
– Digits 3 & 4 = Material Grade
– Last digit 2 = Burnished (All cable cores have been burnished to remove the sharp edges)
Fair-Rite offers a broad selection of ferrite EMI suppression cable cores in several materials with guaranteed minimum impedance specifications.
For smaller suppression parts, refer to the section EMI Suppression Beads.
Our Expanded Cable and Suppressor Kit (part number 0199000005) contains a selection of these suppression cores.
For any cable suppression core not listed here, feel free to contact our customer service group for availability and pricing.
