How do the type numbers relate to things like permiability?
No logic that I've been able to figure out. They are named by their
manufacturers.
How are they sized?
For applications and conductor sizes that customers tell the mfrs they
want. Just like batteries. :)
Who are the makers of there ferrites.
There are a bunch, but only one that provides detailed engineering data
on their products. That company is Fair-Rite.
I would like to learn more and also look into buying from the major producers
like TDK, Tokin, or Siemens.
I would too, but I've been unable to find tech data on their products
that tells me enough to even know their fundamental characteristics.
Will other core shapes work?
Other than what? For use at HF, we must wind multiple turns around a
core that provides a complete magnetic path, so we need cores with a
round opening. Rods do NOT work for chokes.
I've posted a link to my tutorial. It explains a lot of things about
ferrites and how to use them.
