Technical Data by Size

General

Technical values of magnet wires often depend upon 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:

  • IEC 60317 for Europe and Asia
  • JIS C3202 for Asia
  • NEMA MW 1000C (inch) and NEMA MW 1000C metric (mm) for America

Printversions can be found below the individual tabs.
