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.
For Ribbon & Flex Cables
*0 = No End Clip
*M = Metal Clip
*P = Plastic Clip
*A = Hinged Case
Custom Parts with double sided mounting tape are available.
** The “D” & “E” dimensions for 28S, split, two piece cores must be
doubled for total assembled dimensions. “D” & “E” dimensions shown
for hinged case parts are for a complete assemby.
