For retrofit and post-assembly operations, Steward offers a selection of “split”
components. Similar in performance to Steward’s one piece core designs, these
split ferrite cores provide excellent common and differential mode EMI suppres-
sion on round cable assemblies. Lightweight, inexpensive plastic snap-on cases
provide secure closure of the split cores onto the cable.
