Round Cable EMI Suppression Cores

(2643801402)

Part Number: 2643801402

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.

The column “H (Oe)” gives for each bead the calculated dc bias field in oersted for 1 turn and 1 ampere direct current. The

actual dc H field in the application is this value of “H” times the actual NI (ampere- turn) product. For the effect of the dc bias

on the impedance of the bead material, see figures 18-23 in the application note How to choose Ferrite Components for EMI

Suppression.

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.
