Common sense: the diameter specified in the specifications of the enameled wire refers to the diameter of the bare copper wire, apart from the thickness of the paint insulator.
The diameter of the enameled wire measured with a gauge is the outer diameter, including the thickness of the paint insulation, and the measured size is usually larger than the size of the specification standard.
The product in this link is a copper wire, and the coil is included. There are different colors and sizes of coils.
Please know that the copper wires of 1.3mm and above specifications are relatively thick and cannot be straightened after being wound.
The thickened tree is not easy to damage. The shaft holes at both ends are the same size, and are more convenient to use. When the thin copper wire is wound, the coil should be placed upright to allow the copper wire to fall naturally and then wound. Please notice

Qa-1 is equivalent to 2uew, and its insulating layer is polyurethane, which has good direct weldability at 360 ~ 400.
Main Features: It has good direct welding performance, can avoid peeling the film during the wrapping process, and effectively improve the working efficiency; The tangent dielectric loss angle is small, and has a good "Q" value at high frequency characteristics; No pinhole in stretching and bending, suitable for high-speed winding; It has good solvent resistance characteristics for solvents and hardeners used in general containing water.
Application: Widely used in high frequency transformer, inductance coil, relay, motor, winding coil electrical instrument with long-term operating temperature below 155.
