Does it matter what size wire you use when winding toroids?
Thanks,

Depends...but mostly yes.. Reasons: heating due to DC resistance heating due to AC resistance (skin effect, proximity effect) limited window area Resonant frequency,Q To stay within single layer, if needed. D from BC

Ahh. Okay, so if my primary concern is resonant frequency and higher Q, would larger guage wire help these? I'm talking about 24 guage rather than
32, or 32 rather than 36. And this would be in a receiver.Oh, and what is meant by limited window area?
Thanks,
Dave

Larger wire means better Q, but multiple wires may be better than a single solid wire.
Limited window is the physical space available for wire.

Time to read up on 'skin effect' and 'proximity effect'. While your at it, check out 'Litz wire'. Paul Mathews

Thank you, Paul. I will check those out.
And thank you, D from BC, for the fundamental cut to the chase. For some reason my news server didn't pick up your second reply, only your first reply. I suspected large wire meant higher Q, and appreciate your confirmation of that.
I've got some research to do, and now know more or less where to look. Much appreciated.
