Shanghai Metal Corporation is a leading Electrolytic capacitor supplier and manufacturer.

The aluminum electrolytic capacitor is a general-purpose electrolytic capacitor made of aluminum material with good electrical properties, wide application range and high reliability. It is made of an aluminum cylinder as a negative electrode, which is filled with a liquid electrolyte, and is inserted into a bent aluminum strip as a positive electrode.

The core is made up of an anode aluminum foil, a liner paper impregnated with an electrolyte, a cathode aluminum foil, a natural oxide film, etc., and the core is impregnated with an electrolyte and sealed with an aluminum shell and a rubber cover to form an electrolysis capacitor. In general, aluminum electrolytic capacitors have a plastic sleeve on the outside of the aluminum casing. The casing is colorful in color, and it is not only aesthetically pleasing but has a specific meaning.

A capacitor is an energy storage component used in circuits for tuning, filtering, coupling, bypassing, energy conversion, and delay. Capacitors are often called capacitors. According to its structure, it can be divided into fixed capacitors, semi-variable capacitors and variable capacitors.

The product has 30 types and thousands of specifications, and is widely used in air conditioners, tape recorders, washing machines, communication machines and other household appliances and electronic machines, instruments and meters.


Shanghai Metal Corporation is a professional manufacture and supplier of electrolytic capacitor, Mirror Finish/Reflective Aluminum SheetEnameled Aluminum Wire, with high quality and reasonable price. We also supply Aluminum Foil ,Aluminum Foil Container. If you want to know more about our Aluminum products or Aluminum electrolytic capacitor price,please feel free to contact us, we will reply you within 24 hours.

Aluminum electrolytic capacitors are characterized by large capacity, but large leakage, large error, and poor stability. They are often used for AC bypass and filtering, and are also used for signal coupling when the requirements are not high. Electrolytic capacitors have positive and negative poles and cannot be reversed during use.
