Product Details
3UEW155 Ultra fine enameled copper wire for watch / hearing aid
One of the greatest advantages of the 0.012mm super thin enameled
copper wire is its ultra-thin diameter.
The thin wire allows for easy winding and high precision, making it
perfect for use in precision instruments such as medical equipment,
scientific instruments, and electronics.
The ultra-thin diameter also offers excellent insulation, which
helps prevent short circuits and other electrical problems
