Multiple single turn or multi-turn printed circuit EMI suppression beads are available in two Fair-
Rite materials. The broadband 44 material and in the high frequency 52 material grade. PC Beads
are made in two standard component heights.

Wires are oxygen free high conductivity copper with a lead-free tin coating. If required PC Beads can be supplied
The minimum guaranteed impedance is the listed impedance less 20%.
The PC Beads in 44 material are measured on the 4193A Vector Impedance Analyzer. The 52 PC Beads are tested
Parts with a "1" as the last digit of the part number are supplied with a minimum wire length "F" dimension of 2.4 mm
(.095"). A longer minimum wire length of 3.1 mm (.125") is also available, these parts have a "2" as the last digit.
with a tin/lead coating. Wires on top of the beads are covered with a layer of epoxy.
PC Beads are controlled for impedance only. The impedances listed are typical values. Minimum impedance values
are specified for the + marked frequencies.
for impedance on the 4191A RF Impedance Analyzer.
Recommended operating and storage temperature for the PC Beads is -55
Performance curves for all PC beads are on the Fair-Rite Products CD-ROM.
For equivalent PC Beads suitable for surface mounting see pages 38-41.
Explanation of Part Numbers: Digits 1&2 = product class, 3&4 = material grade and last digit 1 = standard wire
length 2.4 mm (.095") minimum, 2 longer wire length 3.1 mm (.125") minimum.
