The capacitor aluminum foil used is divided into three types: cathode aluminum foil, with a thickness of 0.015mm to 0.06mm; high-voltage aluminum foil, with thickness of 0.065mm-0.1mm, and the aluminum foil is required to be produced with high-purity aluminum; the thickness of the low-pressure aluminum foil is 0.06mm-0.1mm.
The thickness of aluminum foil for capacitor is 0.006mm, and the width can be made 500mm, and specific requirements can be customized. 1060 aluminum foil has the characteristics of high plasticity, corrosion resistance, electrical conductivity and thermal conductivity.
In comparison to other dielectric, similar voltage endurance is provided by dielectrics even if thickness ("d" in the above formula) is thin. By etching the surface of aluminum foil, the effective area of the foil can be enlarged 80~100 times for low voltage capacitors and 30~40 times for middle / high voltage capacitors.
The so called foil capacitor has electrodes consisting of aluminum, 5…10 μm (0.2…0.4 mils) thick. Every turn in a capacitor winding adds at least 2×5 μm (2×0.2 mils) metal foil + dielectric which means that the electrodes in a low voltage capacitor accounts for the greater part of the volume.
A 0.05~0.11 mm thick anode foil and a 0.02~0.05 mm thick cathode foil are continuously etched electrochemically in a chloride solution with an AC or DC current. This enlarges the effective surface area of the aluminum foils to attain smaller capacitor sizes. The process develops aluminum oxide (Al203) to form a capacitor dielectric.
In order to increase the surface area by tens upon hundreds of times, aluminum foil for capacitors is treated electrochemically. However, while the greater surface area results in improved capacitance, bending strength tends to decrease.
