These RFI kits are specifically selected to cure most household computer device RFI problems. It contains ferrite toroids for AC or DC power supply protection and Snap On ferrite spli beads selected to eliminate RFI from 1 to 1000 Mhz. The beads are easy to use, don’t require modification of the protected equipment and work in almost all cases, even when plug-in filters fail.
