inductor saturation current
(1/4) > >>
Simon:
i am looking at inductors to use in a power filter. i found what seemed to be too good to be true, a 33µH inductor with 30A constant current. But mwa, mwa, mwaaaaaaar it has a saturation current of less than 3A! surely this is wrong? what use will the inductor be after it saturates at 3A

Marco:
Saturable reactor? :)
ogden:
Everything is OK. RMS current is "DC rated" current handling capability of wire alone. Obviously you pick inductor by it's saturation current.

dmills:
More that you can run em HOT, and that the losses stay small due to the over sized winding (Also, you should be using the -BHA variant for high saturation).
I have used such when I was trying to minimise temperature rise.

a 3A inductor that doesn't turn into a fuse until 30A ..
