5mmx0.7mm AIW 220 Rectangular Flat Enameled Copper Wire For Automotive
Here is the structure of rectangular enameled copper wire.
Flat copper wire is not like cubic shape with right angel at the intersection between width and thickness. From its section, it clearly show that is oval shape on its width side, therefore here is an angle called ‘R Angle’ that is can be customized


1.Higher Space Factor: In the same winding space, the cross-section area of flat copperwire is larger than round copper wire. It has higher space factor, smaller resistance and can through larger current if coilsare made by flat wire, and prevent the over-heat of electronic products. It is more applicable to high load demand.
2. Larger Cross Section . Larger cross section in comparison with round wire, that improve the skin effect and reduce losses of high frequency current. And larger cross section with better heat dissipation performance, it is more applicable to high frequency transduction
3. Better space factor. Up to 96%, that make the complete product smaller, lighter,thinner and better performance
