Customer ServiceThe electrolyte also functions to repair the dielectric layer. This process seals the element using the aluminum can case and sealing materials (rubber,rubber-lined cover, etc.) for keeping the case airtight. The process of applying voltage to a post-sealed capacitor at high tem-perature is called “aging”.
Attach rubber bung / rubber-lined terminal plate / molded terminal plate to impregnated element and seal it with the aluminum case. The sealed capacitor is then covered with sleeve made of a heat shrinkable resin. The purpose of sleeve is to indicate key information of the capacitor.

The capacitor market is complex, with many product geometries, designs, properties and applications. New technologies and the demand for improved productivity levels have a high impact on the materials used for the construction of capacitors. These materials must meet the rigorous demands of the industry.
Some characteristics of an aluminum electrolytic capacitor are temperature-dependent. The higher the temperature is, the more deteriorated the capacitor will be. An increase in tem-perature accelerates the increase in leakage current and tan δ and the decrease in capacitance.
They must provide sealing and mechanical, thermal and chemical resistance. Capacitors can be damaged in many ways, including internal faults or external overloads that can cause an explosion, especially in devices like AC film capacitors with relatively high energy content.
