Round Cable EMI Suppression Cores (2643626302) Part Number: 2643626302 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 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. Typical Impedance () 10 MHz 43 + 25 MHz 63 + 100 MHz 87 250 MHz 106 Electrical Properties H(Oe) 0.29 Suppression cable cores are controlled for impedances only. Minimum impedance values are specified for the + marked frequencies. The minimum impedance is listed on our catalog drawing. Catalog Drawing Single turn impedance tests for 31, 43 and 46 material cores are performed on the E4991A/ HP4291B Impedance Analyzer. The 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. CSV Download Fair- Rite Products Corp.
