Re: Help with inductace value on ferrite core
Actually, some of what are normally seen as RFI ferrites like Fair-Rite number 43 make rather good HF transformers.
For any ferrite, there is a low band where it makes insufficient inductance to bother with, then there is a band where it makes useful inductors of low loss/high Q. Then there is a band where the losses have grown, but it is still useful as a reasonably efficient transformer, and in the highest band losses have grown to make a good RFI absorber.
Different materials just put the boundaries in different places.
