300g Red Magnetic Wire 0.2mm QA Enameled Copper Wire Magnetic Coil Winding for Electric Machine DIY Electromagnet Making (Color : 0.25mm, Size : Red)

300g/pcs Polyurethane Enameled Copper Wire Varnished Diameter 0.1mm To 1.5mm QA-1/155 2UEW For Transformer Wire JumperQa-1 is equivalent to 2uew, and its insulating layer is polyurethane, which has good direct weldability at 360 ~ 400 .Main characteristics: it has good direct welding performance, can avoid peeling the film during winding process, and effectively improve the working efficiency; the dielectric loss angle tangent is small, and has good "Q" value characteristics under high frequency; 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, electrical instrument coil winding with long-term working temperature below 155 .Common sense: The diameter referred to in the specifications of the enameled wire refers to the diameter of the bare copper wire, excluding the thickness of the insulating varnish. The diameter of the enameled wire measured with a caliper is the outer diameter including the thickness of the insulating paint, and the measured size is usually larger than the size of the standard specification.The product in this link is a copper wire, and the spool is included. There are different colors and sizes of spools. Please know that copper wires of 1.3mm and above specifications are relatively thick and cannot be straightened after being wound.UEW is the representation of Japanese standards. Both Taiwan and South Korean are represented by UEW. QA is the representation of national standards and international standards. The difference between them is that the range of UEW outer diameter is relatively loose, and the others are basically the same. Note: 2uew = qa-1 1uew = Qa-2Q in qa-1 is the series code, the first pinyin letter of paint.A is polyurethane paint, the first piny
