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.Fair-Rite Product s Catalog Part Data Sheet, 2743009112 Printed: 2010-11-09 Fair-Rite Products Corp.

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 turn is defined as a single pass through a hole. l/A - Core Constant l e: Effective Path Length Ae: Effective Cross-Sectional AreaL Ve: Effective Core Volume AL- Inductance Factor ( N2) Nl - Value of dc Ampere-turns N/AWG - Number of Turns/Wire Size for Test Coil
