These flat cable snap-its are available in two ferrite materials, 31 and 43. The polypropylene cases are meeting the RoHS restrictions of hazardous substances and have a flammability rating of UL94 V-0. -Flat cable snap-it assemblies are controlled for impedances only. Minimum impedance values are specified for the + marked frequencies. The minimum impedance is typically the listed impedance less 20%. -Centered, single turn impedance tests on the 31 and 43 material parts are performed on the 4193A Vector Impedance Analyzer. Cores are tested with the shortest practical wire length. -The 'Expanded Cable and Suppressor Kit' (Part number 0199000005) contains several flat cable snap-it assemblies. -Explanation of Part Numbers: Digits 1 & 2 = product class and 3 & 4 = material grade.

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 1/2 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, 0431163951 Printed: 2013-07-03 Fair-Rite Products Corp.
