Ferrite filter products can help speed up digital devices by suppressing common mode current from RFI sources OR prevent digital devices from emitting RFI on its connecting cables and power supply lines.
This ferrrite Multi-Ring/Multi-Snap-On Combo Pack is a convenient solution for troubleshooting RFI/EMI (200 - 2000 MHz) with various diameter cables ranging from 1/4" 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. This frequency range is used in switching power supplies, variable speed motors, LED light dimmers and many other DC control circuits. Use on inputs and outputs of these devices to reduce or eliminate RFI.
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:
