RFI/EMI Solutions from KHz to GHz
The Ferrite Snap On, Ring and slip on sampler Pack is a convenient solution for
troubleshooting RFI/EMI with various diameter cables ranging from 1/4″
to 1.4″ for use as either single turn or multiple turn ferrite chokes using ferrite rings, slip on beads and snap on beads.
The filters are useful for RF coax, AC/DC power cables, and device interconnection cables.
Always use a snap on or ring with a larger inside diameter than the diameter of the cable and use multiple turns if possible (2 turns through the snap on is the same as 4 snap ons with 1 turn). Included in these combo packs are our most popular snap on sizes as follows:
F240-31 ring – 1.4 inch ID – 2 pieces
