Hi,

For a filter inductor in an LC filter, does the inductor size (core volume) scale linearly with inductance * current rating^2, all other
variables the same, ie. core material, frequency etc.

Also I need some toroid cores for 200kHz LC filters, 250uH and 50Amps
peak current, are these going to be huge cores and what core materials
would be best to use, ferrite or powder cores?

I've downloaded the www.magneticsinc.com "Magnetics Inductor Design
Using Powder Cores" program:

cheers,
Jamie,
I have your LCLC filter designed with all part numbers. I will sell it to you for a bottle of tequila.
What say you?
Harry
