0.4 - 0.8mm MM SOLDERABLE POLYURTHANE ENAMELED COPPER WIRE
Enameled wire is a copper or aluminium wire coated with a very thin
layer of insulation. It is used in the construction of
transformers, inductors, motors, speakers, hard disk head
actuators, electromagnets, and other applications that require
tight coils of insulated wire.
The wire itself is most often fully annealed, electrolytically
refined copper. Aluminium magnet wire is sometimes used for large
transformers and motors. The insulation is typically made of tough
polymer film materials rather than enamel, as the name might
suggest.
