This utility model relates to the field of electrical component technology, specifically a high-capacity
electrolytic capacitor, including a high-capacity
capacitor core with a multi-layered protective structure on its surface. This utility model provides the
capacitor with high capacity through the high-capacity
capacitor core; the explosion-proof shell in the multi-layered protective structure prevents serious damage from explosion when the
internal pressure of the capacitor is abnormal; the buffer filler area, located between the explosion-proof shell and the outer wall of the high-capacity capacitor core, buffers external impacts and protects the core; an anti-
corrosion coating is applied to the outer wall of the explosion-proof shell to enhance its
corrosion resistance; terminals are connected to the positive and negative terminals of the high-capacity capacitor core for easy
external circuit connection; threaded mounting holes are used to install the terminals, ensuring a stable connection; positive and negative markings are placed on the edge of the opening of each threaded mounting hole, making it easy for users to distinguish between the positive and negative terminals and thus correctly connect the circuit.
