Product Overview

Surface mount common-mode beads from Fair-Rite provide a common magnetic path for flux generated by current to the load and the return current. This current compensation results in zero magnetic flux in the bead. The wires are oxygen-free, high-conductivity copper with 100% matte tin plating over a nickel undercoating. These SM Beads meet solderability specifications when tested in accordance with MIL-STD-202, method 208, achieving at least 95% solder coverage. They also meet the resistance to soldering requirements of EIA-186-10E (2605 C for 101 seconds) after preheating to within 100 C of soldering temperature. Recommended storage and operation temperature is -55 C to 125 C. A Surface Mount Bead Kit (part number 0199000025) is available for prototype evaluation.

Packaging Options:

SM Beads are supplied taped and reeled per EIA 481 and IEC 60286-3 standards on 12 mm, 16 mm, and 24 mm tape widths.
Taped and reeled parts are supplied on a 13 reel.
SM Beads can also be supplied not taped and reeled, in which case they are bulk packed. This packing method changes the last digit of the part number to a 6.

Land Patterns: Suggested land patterns are in accordance with the latest revision of IPC-7351.

Testing & Measurement:

SM Beads are controlled for impedance limits only. Minimum impedance values are specified for the + marked frequencies.
Impedance measurement for 44 materials is performed on the 4193 Vector Impedance Analyzer.
Impedance measurement for 52 SM Beads is performed on the 4291A RF Impedance Analyzer.

For any SM Bead requirement not listed, please contact customer service for availability and pricing.
