0.4 - 0.8mm Solderable Polyurethane Enameled Copper Wire
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.
