coils

[cte72]

I think I know but I would like some comformation. What's the difference between a micro coil and a macro coil

Nano coil = less than 1.4mm ID
Micro coil = 1.5-1.9mm ID
Standard coil = 2-2.9mm ID
Macro coil = 3mm ID or larger

Then you have Spaced coils which have gaps between the wraps and Contact coils where the wraps are in contact with each other.
