Aluminum electrolytic capacitors are widely used in various conventional electronic products, such as power adapters, inverters, fluorescent lighting fixtures and communication equipment. DCM822T350DG2B is a particular type of aluminum electrolytic capacitor popularly used in such industries.

Application Field

DCM822T350DG2B is designed for use in electronic devices requiring high voltage rating, as well as for products that use pulse or transient current. Such products include, but are not limited to: digital cameras, digital camcorders, DVDR/DVDRW players, digital set-top boxes, and network video recorders (NVR). It is also suitable for high power applications such as LCD TVs and audio devices, including blu-ray players.

The DCM822T350DG2B can also be used for inverter circuits and power supplies, and its socket connection design and aluminium foil insulation provide excellent protection for electrical overloads and potential shorts. The DCM822T350DG2B can also be used in automobiles, in the form of secondary igniters and starter motor controls.

Working Principle

Aluminum electrolytic capacitors, such as the DCM822T350DG2B, work on the principle of the electrolytic action between electrically charged anodes and counter-ions within a solution of aluminium oxide. The electrolyte is divided into two distinct layers: the anode and the cathode. The anode is composed of a metal foil core and a layer of dielectric material, while the cathode is a layer of electrolyte and an dielectric material.

When a voltage is applied to the aluminum electrolytic capacitor, charged ions move from the anode to the cathode, attracted by the electric field. This results in the formation of a film of oxide on the cathode. This changes the capacitor\'s capacitance, giving it the ability to store an electrical charge. The electrolyte is the medium that serves to conduct current between the anode and the cathode when a voltage is applied.

The oxide film created on the electrolyte\'s surface also serves to protect the capacitor from breakdown and also to prevent it from failing due the excess amount of current. This makes aluminum electrolytic capacitors particularly suitable for high voltage applications, such as the ones mentioned earlier.
