Flat Cable EMI Suppression Cores (2643168651)
Part Number: 2643168651
43 SPLIT 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.
