Abstract
The invention discloses an aluminum electrolytic capacitor. The aluminum electrolytic capacitor comprises a core package with a polar outgoing line, a polar outgoing line guiding pin led out from the core package, and a packaging metal outer shell wrapping the core package, wherein the bottom of the packaging metal outer shell adopts an interlayer design, an anti-explosion gasket is arranged between the bottom of the packaging metal outer shell and the bottom of the core package, and an air passage is formed among the anti-explosion gasket, the bottom of the core package and the packaging metal outer shell. When the aluminum electrolytic capacitor is exploded, airflow is buffered through the air passage, and therefore impact generated in the explosion process is lowered. Besides, broken pieces of aluminum foils and isolation paper are effectively filtered, only steam is safely released and decompressed finally, and no broken piece of electric sparks is caused. Therefore, the aluminum electrolytic capacitor is safe and reliable to use.
