98 14th Edition Split Round Cable EMI Suppression Cores Suppression cores for round cables are available for a range of cable diameters. Installed around a cable, these 43 and 44 material cores, provide common-mode filtering for multi-strand cables and differential mode filtering for single conductors. Polypropylene cases make the assembly of the core halves a snap. Cores are easily installed in equipment where a retrofit proves necessary. See page 101 for available cases. Cores are controlled for impedance limits only. Two cores making a set are tested for impedance with a single turn, using a Hewlett Packard HP 4193A Vector Impedance Meter. Cores are sold as pieces. For one piece round cable EMI suppression cores, see page 94. For split round cable EMI suppression cores assembled into cases, see page 101. For impedance vs. frequency curves, see Figures 3-12. For any split round cable EMI suppression core requirement not listed in the catalog, please contact our customer service group for availability and pricing. The Expanded Cable and Connector EMI Suppressor Kit (part number 0199000005) contains a selection of these suppression cores. See page 92.
