Custom super thin 0.05mm high voltage PI film taped copper litz wire
Film-covered wire is a wire material commonly used in electronic products. Its interior is enamelled copper stranded wire, and the outer layer is wrapped with PI film or PET film.

This wire is mainly designed to meet the requirements of modern electronic products for miniaturization, high performance, and high reliability. It is widely used in communications, computers, mobile phones, tablet computers, digital products and other fields.

The biggest feature of film-covered wire is "high precision, stable quality, and long service life", and these advantages are exactly what electronic products need. At the same time, in high-frequency applications, the anti-interference performance of film-covered wires is also superior to other ordinary wires.
