must be a lot of fun to get a sliced toroid pieces back into one torus...
But if you cut it with a numerical controlled cutter it should be ok.
Pafi I couldn't see the exact link
But "multi gapped" toroid sounds like marketing speak for powdered iron toroids like the ones from Micrometals Inc. and Amidon.
I don't know what it is.
I think you can. There is no specific link, it's a picture on the main page of Yageo portal. Look at the attachment!
It would be distributed air gap, but I don't search for this. I need MnZn ferrite, for example 3F3, 3C95, and many (at least 4) well defined, rectangular small gaps. Powdered metal has huge loss.
Structurally any more gaps than one will be problematic for the toroid. Also EMI will radiate worse, ie at each gap.
What are the issues with having a larger single gap only?
Maybe there are new lower loss and higher temp powdered iron material mixes that can work,
Have you looked at the cores used on newer PC mother boards?
I don't know what it is.
Will it be of any help for you if Give him some toroids to cut and see what is the result?
If you want to have the best and sheap lpf contact me i test all toroidal material and i find the bestI don't know what it is.
