USB etc Cables - what function does the 'lump' perform.
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?

It contains precious metal, which justifies the £14.99 price tag from some retailers ;-)

If you're referring to what I think you are, it's called a ferrite bead and is to help reduce interference:

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.
