Default 10uH 3A inductor for class-D amp


I've been looking for a 10uH 3A inductor for my tripath ta2020 build. Farnell UK doesn't have any and both mouser and newark are too expensive shipping vise.

Do any one know of another online store selling chokes in Europe? The TA2020's datasheet recommends a 3A 10% choke and those aren't that easy to find.

How big impact on the sound will it have if I choose a 20% one?

The wurth is said to sound better than the arjenhelder one. You will only hear an impact if the coils are not matched properly. As they tend to come from the same batch, this is not an issue.

Besides- They are cheap, buy a few of them and try them out

You will find a t106-2 core on ebay and wind on a meter of enamelled copper wire.
Takes about 5 minutes and is the cheapest option.
