In electrolytic capacitors, cathode foil (also known as negative foil) plays a vital role, with 1070 electronic foil being a preferred material for many applications. Due to its relatively thin oxide layer, cathode foil has a limited impact on high-voltage capacitors. However, in low-voltage applications, expanding its surface area significantly enhances performance. This characteristic makes material selection and production processes for cathode foil one of the key factors determining capacitor quality.
Common electronic foil materials in the market include 1070 aluminum foil and 3003 aluminum foil. These materials undergo specialized etching processes to increase surface area, thereby improving electrostatic capacity. Notably, parameters such as surface temperature, roughness, and oil content during rolling directly affect etching results. Manufacturers must strictly control these factors to ensure product stability and reliability.
