52 PC BEAD
Explanation of Part Numbers:
– Digits 1 & 2 = Product Class
– Digits 3 & 4 = Material Grade
– Last digit 1 = Standard Wire Length 2.4 mm (0.095″) Minimum, 2 = Wire Length 3.1 mm (0.122) Minimum
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.
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.
Recommended operating and storage temperature for the PC Beads is -55 °C to +125 °C.
PC Beads can be supplied with lower component heights “C”. Also, the wire length “F” can be modified to specific requirements.

PC Beads are controlled for impedance only. Minimum impedance values are specified for the + marked frequencies. The minimum impedance is listed on our catalog drawing.
The PC Beads in 44 material are measured on the E4990A Impedance Analyzer. The 52 PC Beads are tested for impedance on the E4991A / HP4291B Impedance Analyzer.
