Round Cable EMI Suppression Cores (2643802702)
Part Number: 2643802702
43 ROUND CABLE CORE
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.
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 4193A Vector Impedance Meter. The 61 material parts are tested on the 4191A RF Impedance Analyzer and 75 material parts are tested on the 4285A LCR Meter. Cores are tested with the shortest practical wire length.
|Typical Impendance (Ω)|
This NiZn is our most popular ferrite for suppression of conducted EMI from 20 MHz to 250 MHz. This material is also used for inductive applications such as high frequency common-mode chokes.
