Fair-Rite offers a broad selection of round cable EMI suppression cores with guaranteed
impedance specifications over a wide frequency range.
• The “H” column gives for each core size the calculated dc
• For typical impedance vs. frequency curves, see Figures 1-5.
• Round cable EMI suppression cores are controlled for impedance
• For smaller size cores, please refer to our EMI Suppression Beads section found on page 24 of this catalog.
• For any round cable EMI suppression core requirement not listed in the catalog, please contact our customer
• The Expanded Cable and Connector EMI Suppression Kit (part number 0199000005) contains a selection of these

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 core material,
see the graphs on pages 179-180, Figures 16-20.
