Part Type Information
Six and eleven hole beads, in two NiZn materials, are available both as beads (product class 26) and wound with tinned copper
wire in several winding configurations (product class 29).
-Parts with a '1' as the last digit of the part number are supplied bulk packed. Wound beads with part numbers 29--666631 and
29--666651 can be supplied radially taped and reeled per IEC 60286-1 and EIA 468-B standards. For these taped and reeled
wound beads the last digit of the part number is a '4'. Taped and reeled wound beads are supplied 500 pieces on a 13'' reel.
-Wire used for winding is oxygen free high conductivity copper with 100% matte tin plating over a nickel undercoating.
-Beads are controlled for impedance limits only. Minimum impedance values are specified for the + marked frequencies. The
minimum impedance is typically the listed impedance less 20%. The 44 material beads and wound beads are tested on the
4193A Vector Impedance Meter. The 61 material parts on the 4291A RF Impedance Analyzer.
-Recommended storage temperature and operating temperature is -55°C to 125°C
-For any wound bead requirement not listed in here, please contact our customer service group for
availability and pricing.
-Explanation of Part Numbers: Digits 1&2 = product class, 3&4 = material grade and last digit 1 = bulk packed, 4 = 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.
