PowerWerx 20 amp noise filter:




I bought this filter while I was looking for a decent retail filter for 12v at higher current. The construction
was a little disappointing, with the choke inside the crude wrapping being a very thin wire (#18 or so?) which
was wound with many turns around a transformer core, which leads me to question the current rating.
