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 a lead-free tin coating. If required, PC Beads can be supplied with wires with a tin/lead coating. These parts, identical in performance to the lead-free parts, have an "L" suffix. 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. 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 for impedance on the 4191A RF Impedance Analyzer.

• Recommended operating and storage temperature for the PC Beads is -55 ^oC to +125 ^oC.

• Performance curves for individual components can be viewed by clicking on the part number in the chart.

• 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.
