Multi-Strand Enameled Copper Wire - 0.31mm Diameter, 20-Strand, 1kg

1kg spool of multi-strand enameled copper wire with a 0.31mm diameter per filament and 20 strands. Construction: inner copper conductor coated with an enamel/polyester insulating finish — also referred to as insulated copper wire, internal copper, surface insulating paint, or polyester patent leather. Key qualities: flexible and robust so it won’t break during winding, and maintains a natural color. Soldering: supports direct welding/soldering without the need to scratch or remove the insulating layer. Applications: ideal for winding and building transformers, inductors, motors, speakers, potentiometers and similar components. As a magnet wire, it converts electric current into magnetic fields and is widely used for transformers, coil winding, solenoids, inductive coils, speaker coils, electromagnets and insulated wire coil assemblies.
