Self Source BOM
« on: November 17, 2012, 08:19:59 AM »
Hi there , just looking through the BOM and build it guide , is there an ampage and tolerance suggestion for the 10uH inductor?
I have never seen one quite like the one in the photo , any suggestions for sourcing one at Farnell, as I live just down the road from them.
cheers and regards

This one is just a noise filter that can be usefull with bad USB power.
I've read some theory about it but never really find the result really obvious.
Shortcut it if you cannot find one...

From memory, between 10uH and 20uH should be OK... I bought mine on ebay.
The whole preenFM currant go through it so it should accept something like 200mA.
