Broadband EMI Ferrite Split/Snap-On Cores

In Plastic Cases

For retrot 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.

For Round Cables & Wiring Harnesses

- 0A0 = White Plastic Snap On Case

- 0A2 = Black Plastic Snap On Case
