Part Type Information
Ferrite suppression beads are supplied assembled on tinned copper wire for automated circuit board assembly.
-Parts with a '2' as the last digit of the part number are supplied taped and reeled per IEC 60286-1 and EIA
RS-296-F standards. Taped and reeled parts are supplied 4500 pieces on a 14'' reel. Taping details: Component
pitch 5 mm. Inside tape spacing 52.5 mm. Tape width 6 mm.
-Beads-on-leads can be supplied bulk packed. The last digit of bulk packed parts is a '1'.
-Wires are oxygen free high conductivity copper with 100% matte tin plating over a nickel undercoating. The
resistance of the wire is 3.5 mOhm for the 22 AWG and 2.2 mOhm for the 20 AWG wire.
-Beads-on-leads are controlled for impedances only. Minimum impedance values are specified for the + marked
frequencies. The minimum impedance is typically the listed impedance less 20%. The impedances of the 73 & 43
beads-on-leads are measured on the 4193A Vector Impedance Analyzer. The 61 beads-on-leads are tested for impedance
on the 4291A RF Impedance Analyzer.
-For any bead-on lead requirement not listed here, feel free
to contact our customer service group for availability and pricing.
-Our 'Bead-on-Lead Suppression Kit' (part number 0199000028) is available for prototype evaluation.
-Explanation of Part Numbers: Digits 1&2 = product class, 3&4 = material grade and last digit 1 = bulk packed,
2 = taped and reeled.

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.
