2UEW-F Ultra Fine 0.03mm Enameled Copper Wire Magnet Wire For Earphone

One of the outstanding features of this ultra-fine enameled wire is its extremely small diameter.

Our ultra-fine enameled copper wire (also known as magnet wire) is engineered to provide superior insulation without the risk of pinholes. This feature is critical for applications where electrical integrity is critical. The absence of pinholes ensures that the wire maintains its insulation properties, preventing short circuits and improving the overall safety of electronic devices. With temperature options of 155 and 180 degrees Celsius, our ultra-fine wire is ideal for applications that require reliable performance under varying thermal conditions.
