43 ROUND CABLE CORE ASSEMBLY
Explanation of Part Numbers:
– Digits 1 & 2 = Product Class
– Digits 3 & 4 = Material Grade
Round cable snap-it™ can easily accommodate round cables or bundled wires with diameters from 2.5 mm (0.100) to 25.4 mm (1.000). 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 UL 94 V-0.
Many of the snap-it™ parts have round core equivalents. See Round Cable EMI Suppression Cores.
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).
The B dimension is the core inside diameter.

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 31, 43 and 46 material cores are performed on the E4991A/HP4291B Impedance Analyzer. The 61 material parts are tested on the E4991A / HP4291B Impedance Analyzer and 75 material parts are tested on the E4990A Impedance Analyzer. Cores are tested with the shortest practical wire length.

This NiZn is our most popular ferrite for suppression of conducted EMI from 20 MHz to 250 MHz. This material is also used for inductive applications such as high frequency common-mode chokes.
