Abstract

The aluminum electrolytic capacitor comprises a shell with an opening and a core, a rubber plug is arranged at the opening, the core penetrates through the rubber plug and is contained in the shell, a sleeve is arranged outside the shell, and a groove is formed in the circumferential outer wall of the sleeve. According to the aluminum electrolytic capacitor provided by the invention, the service life of the aluminum electrolytic capacitor is prolonged by reducing the water content of the electrolyte, reducing the density of the electrolytic paper and improving the formation voltage of the aluminum foil.

Description

technical field [0001] The invention belongs to the technical field of aluminum electrolytic capacitors, and particularly relates to an aluminum electrolytic capacitor. Background technique [0002] As a common device on electronic circuits, aluminum electrolytic capacitors play the electrical functions of filtering, bypassing, coupling, decoupling, and switching. They are widely used in various electronic circuits. Aluminum electrolytic capacitors can be divided into different types according to different types. Lead type, SMD type, solder chip type, bolt type, and lead type electrolytic capacitors mainly riveted the guide pin on the aluminum foil, and wound it together with the electrolytic paper into a core, soaked in the electrolyte, and sealed it through the casing rubber plug. The final casing is made. According to the product height, it can be divided into 5mm high products, 7mm high products, 9mm high products, and more than 11mm high products. Among them, 7mm high ...
