Ferrite material TDK H7B

[rikkitikki]

Got myself a whole lot of RM14 cores in thismmaterial. Got not much from google, but the usable frequency range is up to about 200 kHz, and general purpose for power applications.
Ui about 2200 ...

Was probably obsolete already in early 90ies, find nothong at TDK webpage either.

Anybody heard about it?

Thanks,, but that is just for the core (in more modern material)
I think I was to fuzzy, I was looking for info of the material H7B.
I got some cores in N67 aswell.

The best option at this stage is to ask szhighstar
