– 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.
The C dimension, the core length, can be modified to suit specific applications.

|Typical Impedance (Ω)|
Suppression cable cores are controlled for impedances only. Minimum impedance values are specified for the + marked frequencies. The minimum impedance is typically the listed impedance less 20%.
Single turn impedance tests for 31, 43 and 46 material cores are performed on the E4991A/HP4291B Impedance Analyzer. The 61 material parts are tested on the E4991A / HP4291B Impedance Analyzer and 75 material parts are tested on the E4990A Impedance Analyzer. Cores are tested with the shortest practical wire length.
|Typical Impendance (Ω)|
A high permeability MnZn ferrite intended for a range of broadband and pulse transformer applications and common-mode inductor designs.
Toroidal cores are available in 75 material.
