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 a lead-free tin plating. -Beads are controlled for impedance limits 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 44 material beads and wound beads are tested on the 4193A Vector Impedance Meter. The 61 material parts on the 4191A 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.

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. l/A - Core Constant Ae : Effective Cross-Sectional Area L AL - Inductance Factor (__ N 2) N/AWG - Number of Turns/Wire Size for Test Coil l e : Effective Path Length Ve : Effective Core Volume Nl - Value of dc Ampere-turns Fair-Rite Product's Catalog Part Data Sheet, 2944666671 Printed: 2010-11-09 Fair-Rite Products Corp.
