Works well...
Torid core ferrites work well, so long as you can somehow reveal the MHz frequency of the noise and match the correct ferrite mix to that and the ferrite will do the rest. It sometimes will require more than one and always by one large enough to loop the cord and or coax of the affected device through it...Verified purchase: YesCondition: New

Good value for easy fix for RFI
Worked great for reducing common mode current and resulting RFI on the feedline for my end fed antenna to my amateur radio transceiver. Where before, the RFI would cause loud noise from my computer speakers while transmitting, after looping my coax through the torroid a few times effectively eliminated the effects.Verified purchase: YesCondition: New

The best material for HF common mode chokes, in my opinion.
If you are 'into' amateur radio. 11 - 13 coax turns wound on the toroid makes an excellent line choke. Suppress common mode currents on your coax.Verified purchase: YesCondition: New

Everybody Needs One
This is a ring of iron filings. The mix of ferrite creates a frequency selective transformer core. Will work on transmission, being careful not to overheat.Verified purchase: YesCondition: New

Works well
I am using this on the USB cable between my amateur radio and my laptop as I was having errors most likely caused by some RFI. All seems to be good now.Verified purchase: YesCondition: New
