speckytecky Posted January 6, 2012 Posted January 6, 2012 A friend recently asked me what that chunky little lump that appears on USB ect cables does. I have always assumed it's some sort of surge protection but couldn't give a defo answer?
andyturpie Posted January 6, 2012 Posted January 6, 2012 It contains precious metal, which justifies the £14.99 price tag from some retailers ;-)
AngryTechnician Posted January 6, 2012 Posted January 6, 2012 If you're referring to what I think you are, it's called a ferrite bead and is to help reduce interference: Ferrite bead - Wikipedia, the free encyclopedia 2
GrumbleDook Posted January 6, 2012 Posted January 6, 2012 Ferrite Bead or choke ... to deal with interference and so on. Had the problem with some devices that they are just not happy with a cable without this ... in particular those which are host powered. 1
Rawns Posted January 6, 2012 Posted January 6, 2012 Well, I learnt something today. Incredible as it's 4:30pm on a Friday!
