Part Type Information
Surface mount beads are available from Fair-Rite in several materials and sizes. Their rugged construction lowers the
dc resistance and increases current carrying capacity compared to plated beads.
-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'.
-The copper conductors have a lead-free tin coating.
-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. The impedances listed are typical values. Minimum impedance
values are specified for the + marked frequencies. The minimum guaranteed impedance is the listed value less 20%.
SM Beads in 73, 43 and 44 materials are measured for impedance on the 4193 Vector Impedance Analyzer. The 52
and 61 SM Beads are tested for impedance on the 4191A RF Impedance Analyzer.
-Recommended storage and operation temperature is -55°C to 125°C.
-The maximum practical current rating for these SM Beads is 5 amps.
-For any SM Bead requirement not listed, please contact our customer service group for availability and pricing.
-Our 'Surface Mount Bead Kit' 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.
