| 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 https://www.mouser.co.uk/ProductDetail/Bourns/PQ2614BLA-330K?qs=sGAEpiMZZMv126LJFLh8y0s%252BS7zpDfrQRB236tWoNWQ%3D |

Saturable reactor? :) |

Everything is OK. RMS current is "DC rated" current handling capability of wire alone. Obviously you pick inductor by it's saturation current. [edit] https://www.vishay.com/docs/34053/definit.pdf |

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. Regards, Dan. |

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