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.
