Class 220 0.45×7.5mm Polyimide Coated Flat Copper Wire Enameled Self Bonding Magnet Wire For Notebook Coil
CLASS 220 0.45×7.5MM POLYIMIDE COATED FLAT COPPER WIRE ENAMELED SELF BONDING MAGNET WIRE FOR NOTEBOOK COIL
Rectuangular or flat enameled copper wire consists two parts: width and thicness.When we describe the size, it likes thickness x width or width x thickness.Today most popular Notebook computers, wireless charger...and many other 3C products, are ever-possible designing to make its shape and structure become as light, thin, short and small as possible; while this development demanding the stricter characteristics of its coil, also resulting the conventional enamelled copper wire unfitted for the trend. This special demand for smaller-dimension and higher-efficiency makes the fiat-shape coil become the mainstream of the future, in response to this brand new trend, the Company successfully developed the "Enamelled Flat Copper Wire" for the market.
APPLICATION
- Notebook coil.
- Coils of printer.
