Abstract

The invention relates to the technical field of capacitors, in particular to a chip-type high-voltage miniaturized long-life aluminum electrolytic capacitor and a manufacturing method thereof. The chip-type high-voltage miniaturized long-life aluminum electrolytic capacitor comprises an aluminum shell, a core, a positive guide pin, a negative guide pin and colloidal particles, a containing groove is formed in one end of the aluminum shell, a clamping part is arranged at the free end, close to a notch of the containing groove, of the aluminum shell in an inward pressing mode, and the core is located in the containing groove; and the positive guide pin and the negative guide pin are both installed on the core, the colloidal particle is located at a notch of the containing groove and seals the notch of the containing groove, the clamping portion abuts against the colloidal particle, and the positive guide pin and the negative guide pin both penetrate through the colloidal particle. According to the invention, the connection strength between the colloidal particles and the aluminum shell is enhanced, so that the colloidal particles are not liable to fall off from the aluminum shell due to the influence of external force, the electrolyte is not liable to leak from the aluminum shell, and the durability of the capacitor is ensured.
