SM Beads (Common Mode) - Fair

Surface mount common-mode beads are available from Fair-Rite in several materials and sizes. The common-mode bead
provides a common magnetic path for the flux generated by the current to the load and the return current from the load.
The current compensation results in zero magnetic flux in the bead.
• SM Beads on 12 mm tape width are supplied taped and reeled per EIA 481-1 and IEC 60286-3 standards. SM Beads on 16 and
24 mm tape widths are supplied taped and reeled per EIA 481-2 and IEC 60286-3 standards. Taped and reeled parts are
supplied on a 13" reel.
• SM Beads can also be supplied not taped and reeled and then are bulk packed. This packing method will change the last digit of
the part number to a "6".
• Wires are oxygen free high conductivity copper with 100% matte tin plating over a nickel undercoating.
• SM Beads meet the solderability specifications when tested in accordance with MIL-STD-202, method 208. After dipping the
mounting site of the bead, the solder surface shall be at least 95% covered with a smooth solder coating. The edges of the
copper strip are not specified as solderable surfaces.
• After preheating the beads to within 100 oC of the soldering temperature, the parts meet the resistance to soldering requirements
of EIA-186-10E, temperature 260±5 oC and time 10±1 seconds.
• Suggested land patterns are in accordance with the latest revision of IPC-7351.
• SM Beads are controlled for impedance limits only. Minimum impedance values are specified for the + marked frequencies. The
minimum impedance is typically the listed value less 20%. SM Beads in 44 materials are measured for impedance on the 4193
Vector Impedance Analyzer. The 52 SM Beads are tested for impedance on the 4291A RF Impedance Analyzer.
• Recommended storage and operation temperature is -55 oC to 125 oC.
• The maximum current rating for these SM Beads is 5 amps.
• Performance curves for these suppression components are our web site.
• For any SM Bead requirement not listed, please contact our customer service group for availability and pricing.
• Our "Surface Mount Bead Kit" (part number 0199000025) is available for prototype evaluation.
• Explanation of Part Numbers: Digits 1&2 = product class, 3&4 = material grade, last digit 6 = bulk packed, 7 = taped and reeled.
