40 AWG 0.08mm UEWF Magnet Winding Wire Ultra Thin Enameled Copper
Wire
Ultra thin enameled copper wire is widely used in precise
electronic device,such as medical device,touch screen, sensors
etc.Our wilre has been tested by European market with different
applications with superexcellent performance. Most manufacture can
only provide natural color or other color but need very hugh
quantity, we can offer you the best solution, color wire with very
low MOQ that will be grealy reduce your costs.
FEATURES
