Part Type Information
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. 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°C to +125°C.
-Explanation of Part Numbers: Digits 1&2 = product class, 3&4 = material grade and last digit 1 = standard wire length 2.4 mm (.095'')

Preferred parts, the suggested choice for new designs,have shorter lead times and are more readily available.
The column H(Oe) gives for each bead the calculated dc bias field in oersted for 1 turn and 1 ampere direct current. The actual dc H field in
the application is this value of H times the actual NI (ampere-turn) product. For the effect of the dc bias on the impedance of the bead material,
see figures 18-23 in the application note How to choose Ferrite Components for EMI Suppression.
A ½ turn is defined as a single pass through a hole.
