electronic aluminum foil

Introduction to electronic foil

In electrolytic capacitors, cathode foil is commonly called cathode foil. Due to the thin oxidation film on the surface of cathode foil, the improvement of cathode foil surface area has little impact on high-voltage capacitors, but has a great impact on low-voltage capacitors. Electrolytic capacitors are widely used in household appliances, computers, communications, industrial control, electric vehicles, electric locomotives and military and aerospace equipment. Electronic aluminum foil produced by Mingtai Aluminum  is mainly negative foil, with alloy types of 1070 and 3003, and the thickness range of which can be processed is 0.012 -- 0.05mm. In the production process, the surface quality, temperature, grain structure, composition and other aspects of the negative electrode foil are strictly controlled.
