Tamicy 60 Pieces Clip-on Ferrite Ring Core RFI EMI Noise Suppressor Cable Clip for 3mm/ 5mm/ 7mm/ 9mm/ 13mm Diameter/Video Cable Power Cord (Black)

Almost anyone should have a bag of these noise reduction devices if they have more than one electronic device around. Clamp one around the power cord of the device causing interference and voila! No more interference. Well, sometimes it works that way. The thing about RFI (Radio Frequency Interference) is that it is sneaky and can get out of its container in lots of different ways, not just the power cord. It usually takes a bit more effort to suppress it than that. But if the RFI emitter was otherwise well designed, than the power cord fix will sometimes help. Sometimes putting the device into a metal container with a tight fitting lid (or its equivalent, also known as a Faraday cage) might be the only way to get the noise suppressed but only if the container is well grounded. The funny thing is that this container could absorb the RFI within it and re-radiate it from the outside depending on a lot of conditions. So , to sum up, these ferrites might work, and if they don't, well, they're cheap so you haven't lost much.

Poco que compartir son cables de muy buena calidad - es todo.-.-.-

Have used nearly all of these they are used to reduce the effect of radio frequency interference. Have not carried out definite testing to determine if within specifications. However they have worked in all all instances where required.

used on the AC power lines to LED lights
