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 a lead-free tin coating. 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. 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
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 4191A RF Impedance Analyzer.
-Preferred beads-on-leads are the suggested choice for new designs. Samples are readily available and orders have
typically shorter lead times than other beads-on-leads. 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.
