Part Number: 2661828302 61 Toroidal Suppression Core Explanation of Part Numbers: – Digits 1 & 2 = Product Class – Digits 3 & 4 = Material Grade – Last digit 2 = Burnished (All cable cores have been burnished to remove the sharp edges) Fair-Rite offers a broad selection of ferrite EMI suppression cable cores in several materials with guaranteed minimum impedance specifications. For smaller suppression parts, refer to the section EMI Suppression Beads. Our Expanded Cable and Suppressor Kit (part number 0199000005) contains a selection of these suppression cores. The C dimension may be modified to suit specific applications. 181 (g) Σl/A : Core Constant, l : Effective Path Length, A : Effective Cross-Sectional Area, V : Effective Core Volume A : Inductance Factor A high frequency NiZn ferrite developed for a range of inductive applications up to 25 MHz. This material is also used in EMI applications for suppression of noise frequencies above 200 MHz. Excellent stability characteristics.
