I want to try our friend John Soper's 5200 switchbox removal mod,as outlined here http://www94.pair.com/jsoper/5200_4p_pwr.html.

I know my way around an electronics store pretty good, but this description from his method:

solder a high current (2A) inductor to where cable was (L value not critical)
Is not helping me at my usual electronics haunts. I've never used an inductor in an application before. I've run the description through Google, but too many different components pop up.

Anyone want to school me about inductors, names, ratings, and what to ask for at the electronics supply place?
