[0002] The core of the capacitor is made of 4 layers of overlapping and winding, including anode aluminum foil, electrolytic paper, cathode aluminum foil, and electrolytic paper. After the core is impregnated with electrolyte, it is sealed with an aluminum shell and a rubber cover to form an electrolytic capacitor. After DC voltage treatment, a layer of oxide film is formed on the anode aluminum foil as a medium. The electrolytic paper serves to isolate the anode aluminum foil and the cathode aluminum foil, and at the same time stores the electrolyte. The anode foil is an electrode, and the oxide film on it is an electrical insulator. The cathode aluminum foil serves as a lead-out electrode. At this time, the anode of the capacitor is an aluminum foil with an Al2O3 dielectric layer formed on the surface, and the cathode is the electrolyte of the capacitor. The positive and negative polarity pins are respectively led out on the anode aluminum foil and the cathode aluminum foil, and then the pins are connected to the external CP line, which is the guide pin.
