The inductance of Rectangular Enameled Copper Wire is called high-current inductance, because the inductance of the round wire cannot reach the set current value under the same size, so a flat coil is produced.

Rectangular enameled copper wire has the lowest resistance under the same size conditions, and the material does not contain lead, which meets the ROHS directive. These characteristics determine that it can replace the previous generation of round copper coils and become a universal product for small handheld electronic devices such as power supplies and PCs, such as IPAD. The reason is due to the advantages of flat coils:

1. The spiral coil is based on a planar structure and is made of flat enameled wire above AIW200. The heat dissipation performance is better than that of Round Enameled Copper Wire, and it can greatly exceed traditional products in terms of air duct heat dissipation;
2. Product optimization design-excellent heat dissipation performance, so that the magnetic core has a higher working index, reduce consumables, reduce the size of the magnetic core, and reduce the number of turns.
3. In the overall design, the original circular structure is changed and the plane design is adopted, which directly increases the surface area and volume of the product, and makes the heat dissipation of the magnetic core and coil more reasonable, scientific and efficient.
