PC Beads (Through Hole) - Fair

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 can be supplied with lower component heights "C". Also, the wire length "F" can be modified to specific requirements.
• Wires are oxygen free high conductivity copper with 100% matte tin plating over a nickel undercoating. Wires on top of the beads
are covered with a layer of epoxy.
• PC Beads are controlled for impedance only. Minimum impedance values are specified for the + marked frequencies. The
minimum impedance is typically 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 for impedance
on the 4291A RF Impedance Analyzer.
• Recommended operating and storage temperature for the PC Beads is -55 oC to +125 oC.
• Performance curves for these suppression components are on our web site.
• Explanation of Part Numbers: Digits 1&2 = product class, 3&4 = material grade and last digit 1 = standard wire length 2.4 mm
(0.095") minimum, 2 = wire length 3.1 mm (0.122”) minimum.
