aluminum foil capacitor

The aluminum foil used in electrolytic capacitors is a corrosive material that works under polar conditions. It has higher requirements for the structure of aluminum foil. The aluminum foil used is divided into three types: cathode foil, with a thickness of 0.015mm to 0.06mm; high-voltage foil, with a thickness The thickness is 0.065mm～0.1mm, and the aluminum foil is required to be produced with high-purity aluminum; the thickness of the low-pressure foil is 0.06mm～0.1mm.
