Round Cable Snap- Its (0444164281)
Part Number: 0444164281
44 ROUND CABLE CORE ASSEMBLY
Explanation of Part Numbers:
– Digits 1 & 2 = Product Class
– Digits 3 & 4 = Material Grade
Round cable snap- its 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).

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.
