[Amps] Queation on toroid core materials

[Will Matney]

Bill,

Really it's over the really low permeability of iron powder compared to ferrite that would make it hard to use a one-turn winding. Iron powder does come in handy though for combiners/splitters though. It's also good for baluns/ununs.

Best,

Will
