EMI Suppression Beads
Fair-Rite offers a broad selection of EMI suppression beads with guaranteed impedance specifica-
tions over a wide frequency range.
• Beads with a “1” as the last digit of the part number
• Beads can be supplied Parylene coated upon request.
• The “H” column gives for each bead size the calculated dc bias field in
• For typical impedance vs. frequency curves for these parts, see Figures 1-6.
• Beads are controlled for impedance limits only. They are tested for impedance with a single turn, using the Hewlett Packard
• For larger size cores, please refer to our Round Cable EMI Suppression Cores section found on pages 94-97.
• For any EMI suppression bead requirement not listed in the catalog, please contact our customer service group for
• The EMI Suppression Bead Kit (part number 0199000019) contains a selection of these cores.

are not burnished, those with the last digit “2” are supplied
burnished to break the sharp edges.
The last digit of the Parylene coated part number is a “4”.
The minimum coating thickness for beads is 0.005mm (.0002").

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