This ferrrite Multi-Ring/Multi-Snap-On 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 RFI filters using ferrite rings and snap ons.
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″/35.6mm ID – 6 pieces
FSB31-3/8 – 3/8″/9.5mm ID – 6 pieces
FSB31-1/2 – 1/2″/12.7mm ID – 5 pieces
