I have 1.25" OD toroid for which I need to specify wire.
Inductor specs:
The wire is 24AWG (thin)
There are only 19 turns - they are separated on the core.
The leads are ~2"long and tightly twisted (4-5 twists per inch).
The inductor sees 200V applied across it's terminals.
Operating temperature will never exceed 50-60 degrees C.
Magnet wire comes to mind, right?
My concerns are:
if enamel is damaged/nicked, twisted leads may short (with
catastrophic consequences)
If/when manufacturing is sent out to China, God knows what kind of
insulation will be used there (we are having problems with Chinese CM
quality)
Here is my question to all the experts:
What is cheaper/easier to manufacture
generic magnet wire with both leads in some flexible tubing (I want
leads to be tightly twisted) OR
make everything out of UL1007 (or equivalent) solid hookup wire
I cannot get a straight answer from our (local assembly house). They
say that magnet wire is cheaper (how much do I save on 19 turns @<5000
units per year???); magnet wire can be purchased with heavy insulation
(how to specify it??); Teflon/shrink tubing is commonly used (is it
cheaper??).
Thank you in advance for your help and sorry for the long posting.
