BROADBAND EMI FERRITE
SPLIT / SNAP-ON CORES IN PLASTIC CASES
FOR ROUND CABLES & WIRING HARNESSES
For retrofit and post-assembly operations, Laird Technologies offers a selection of “split” cores. Similar in performance to the one-
piece core designs, these split ferrite cores provide excellent common and differential mode EMI suppression on round cable and
wire assemblies. Black or white plastic snap-on cases provide secure closure of the split cores onto the cable.
