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 numberare not burnished, those with the last digit “2” are suppliedburnished to break the sharp edges.•Beads can be supplied Parylene coated upon request.The last digit ofthe Parylene coated part number is a “4”.The minimum coating thickness for beads is 0.005mm (.0002").See page 159 for material characteristics of Parylene C.•The “H” column gives for each bead size the calculated dc bias field inoersted for 1 turn and 1 ampere direct current. The actual dc H field inthe application is this value of “H” times the actual NI (ampere - turn) product. For the effect of the dc bias on the impedanceof the bead material, see the graphs on pages 179-180, Figures 16-20.•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 PackardHP 4193A Vector Impedance Meter for beads in 73, 31, and 43 material and the HP 4191A RF Impedance Analyzer for61 material beads.•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 foravailability and pricing.•The EMI Suppression Bead Kit (part number 0199000019) contains a selection of these cores.See page 92.Listed in ascending order of “B” dimension.Part Number**ABC*Wt (g)H (Oe)10 MHz25 MHz100 MHz250 MHz 26739013012673903301
