These assemblies are available in four ferrite material classes to suppress differential or common-mode conducted EMI from 1 MHz into the GHz region. The polypropylene cases are meeting the RoHS restrictions of hazardous substances and have a flammability rating of UL94 V-0. -Round 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%. -Single turn impedance tests for the 31, 43, 44 and 46 material are performed on the 4193A Vector Impedance Analyzer. The 61 material parts are tested on the 4291A RF Impedance Analyzer and 75 material parts are tested on the 4285A LCR Meter. Cores are tested with the shortest practical wire length. -Many of the snap-it parts have round core equivalents. See Round Cable EMI Suppression Cores section of our catalog. - B Dimension is the core Dimension. -Round Cable Snap-it Kits are available for each of the four suppression materials. 31 Snap-It Kit (0199000030), 43 Snap-It Kit (0199000031), 46 Core and Snap-It Kit (0199000032) and 61 Snap-It Kit (0199000033). -Explanation of Part Numbers: Digits 1 & 2 = product class and 3& 4 = material grade.Fair-Rite Product s Catalog Part Data Sheet, 0446176451 Printed: 2014-05-13 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 : Effective Path Length e A : Effective Cross-Sectional Area V : Effective Core Volume e e L A - Inductance Factor ( ) Nl - Value of dc Ampere-turns 2 N L N/AWG - Number of Turns/Wire Size for Test Coil
