Various Sizes Class 220 0.4mm*4.0mm Rectangular Enameled Flat Rectangular Copper Wire
In comparison with round wires, rectangular wires have the advantage of allowing more compact windings, thereby delivering both space and weight savings. The electrical efficiency is also better, which saves energy.
Especially when the wires are meant to be insulated with enamel, the precision of width and thickness as well as the geometry of the corner radius is of great importance for the defect-free use in electrical coil
