This Ferrite Ring and Snap On Combo Pack features our two most popular ferrite filter sizes - the 1.4" ID ring for multiple turns of AC/DC or signal cables and the 1/2" ID snap on for signal cables like ethernet, audio, video, coax or data cables. You get 10 of the rings and ten 1/2" snap on ferrites - plenty to solve a complex RFi problem or several smaller ones.
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).
