UEW 0.026mm Enamelled Round Copper Wire Good Solderability
UEW 0.026mm Enamelled Round Copper Wire Good Solderability
Magnet wire or 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.
FEATURES
-
With good solderability, reduces coil production costs due to elimination of mechanical or chemical stripping.
-
Superior ''Q'' characteristic at high frequencies.
-
Excellent film adhension and flexibility.
-
Extremely resistant to a variety of solvents including most varnishes and hardener catalysts.
