70 15th Edition 15th Edition 71 Round Cable EMI Suppression Cores Listed by frequency range and in ascending order of B dimension. Fair-Rite offers a broad selection of ferrite EMI suppression cable cores in several materials with guaranteed minimum impedance specicfi ations All cable cores have been burnished to remove the sharp edges The column H (Oe) gives for each cable core the calculated dc bias efi ld in oersted for 1 turn and 1 ampere direct current. The actual dc H efi ld in the application, is this value of H times the actual NI (ampere-turns) product. For the effect of the dc bias on the impedance of the core material, see the material graphs on pages 145-146, Figures 18-23 Suppression cable cores are controlled for impedances only. The impedances listed are typical values. Minimum impedance values are speciefi d for the + marked frequencies. The minimum guaranteed impedance is 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. Cores are tested with the shortest practical wire length Performance curves of all listed cable suppression cores are compiled on the Fair-Rite Products CD-ROM For smaller suppression parts, refer to the section EMI Suppression Beads on pages 29-33 For any cable suppression core not listed here, feel free to contact our customer service group for availability and pricing OurExpanded Cable and Connector EMI Suppression Ki (part number 0199000005) contains a selection of these suppression cores.
