Flat Cable EMI Suppression Cores (2631163851) Part Number: 2631163851 31 FULL FLAT CABLE CORE Explanation of Part Numbers: Digits 1 & 2 = Product Class Digits 3 & 4 = Material Grade Flat cable suppression core can accommodate multi- conductors flat cables, in widths from 12.7 mm (0.500) up to 77 mm (3.0). These flat cable cores are available in two ferrite material grades to reduce conducted EMI from 1 MHz to hundreds of MHz. Our Expanded Cable & Suppressor Kit (part number 0199000005) contains a selection of these flat cable cores and clips. Flat Cable Cores are available in selected sizes in the Flex Circuit & Ribbon Cable Core Kit (part number 0199000038). Assembly clips are available for most of the split flat cable cores. See section Flat Cable Cores Assembly clips. Catalog Drawing 3D Model Weight: 51 (g) Dim mm mm tol nominal inch inch misc.
