For Ribbon & Flex Cables
Broadband Split Ferrite Cores
Laird Techologies’ offers a selection of broadband “split” ribbon and flex cores for retrofit and post-
assembly operations. Similar in performance to one piece core designs, these split ferrite cores provide
excellent differential and common mode EMI suppression on flat cable assemblies. Lightweight,
inexpensive metal or plastic end clips and cases provide secure closure of the ferrite onto the flat cable.
