I am designing a coil which will have 2100 turns of 30AWG wire.(adsbygoogle = window.adsbygoogle || []).push({});

The bobbin diameter is 1.045" and the length is 1.28"

From my calculations I will use about 8,420 inches of wire.

I tried an online calc but they did not take into account that the wire I am using has a heavy insulation so it's diamter is about .0115".

As we know things is the real world are usually somewhat different.

My question is how much of an error tolerance I should expect in terms of wire length for the 2100 turns? And should I expect to use more or less wire than calculated?

Any help/suggestions would be greatly appreciated.
