Technical Data for Copper Magnet Wire by Size
Technical values of magnet wires often depend on the diameter of the wire.
Most important are the tolerances for resistance and outer diameter. These and other values are important as engineering support.
Different standards specify these values differently. Therefore the 3 major world standards are shown:
- NEMA MW 1000C (inch) or
- NEMA MW 1000C metric (mm) for North America
- IEC 60317 for Europe
- JIS C3202 for Asia
