Part Type Information
Fair-Rite offers a broad selection of ferrite EMI suppression cable cores in several materials with guaranteed minimum
impedance specifications.
-All cable cores have been burnished to remove the sharp edges.
-The column 'H' (Oe) gives for each cable core the calculated dc bias field in oersted for 1 turn and 1 ampere direct
current. The actual dc H field 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 figures 18-23 in the application note
'How to choose Ferrite Components for EMI Suppression'.
-Suppression cable cores are controlled for impedances only. Minimum impedance values are specified for the + marked
frequencies. The minimum impedance is typically 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.
-For smaller suppression parts, refer to the EMI Suppression Bead section of our catalog.
-For any cable suppression core not listed here, feel free to contact our customer service group for availability and pricing.
-The 'C' dimension, the core length, can be modified to suit specific applications.
-Our Expanded Cable and Suppressor Kit (part number 0199000005) Contains a selection of these suppression cores.
-Explanation of Part Numbers: Digits 1 & 2 =product class, 3 & 4 material grade and last digit 2 = burnished.

Preferred parts, the suggested choice for new designs,have shorter lead times and are more readily available.
The column H(Oe) gives for each bead the calculated dc bias field in oersted for 1 turn and 1 ampere direct current. 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.
A ½ turn is defined as a single pass through a hole.
