The Ferrite Snap On and Ring Combo Pack is a convenient solution for troubleshooting RFI/EMI (1-300 MHz) with various diameter cables ranging from 3/8" to 1.4"/35.6mm for use as either single turn or multiple turn ferrite chokes using ferrite rings and snap ons.

The filters are useful for RF coax, AC/DC power cables, and device interconnection cables.
