Capacitor Cathode Foil
Aluminum foil for electrolytic capacitors is actually a deep-processed product. It is a kind of corrosive material working under polar conditions, which has high requirements on the organization of the aluminum foil. There are three kinds of aluminum foils used for electrolytic capacitor: capacitor cathode foil with thickness of 0.015-0.06mm, high-pressure anode foils with thickness of 0.065-0.1mm, and low-voltage anode foils with thickness of 0.06-0.1mm. The anode foil is made of industrial high-purity aluminum, the mass fraction of which should be greater than or equal to 99.93%, while the purity of the aluminum used for the high-voltage anode should be greater than or equal to 4N. The capacitor cathode foil of electrolytic capacitors is an important part of electrolytic capacitors, and its specification size and quality requirements have an important impact on the performance and stability of capacitors. Generally speaking, the specification size and qu...
