Default Re: Help with inductace value on ferrite core

You're right, however on checking the data sheet, this is a core made for RFI suppression. So the ferrite grade used will be deliberately lossy (to convert RF energy to heat, and to damp any spurious resonances so there is no artificial peak enhancement).

That's why no Al value is specified. People just won't want to use them for transformers!
