Aluminum electrolytic capacitors are electronic components, mainly used to store electric energy. Many occasions need to obtain high capacity in a small volume, so aluminum electrolytic capacitors are widely used in consumer electronics, industrial automation, medical, military and other fields. SN220M010ST is a type of aluminum electrolytic capacitor produced by a well-known capacitor manufacturer. This article will further explain its application field and working principle.

SN220M010ST aluminum electrolytic capacitor is mainly used in equipment such as high-power DC-DC power supply modules, high-performance notebooks, medical instruments and automobile electronic equipment. It has a wide temperature range of -55℃~+125℃ and a long life of up to 3000 hours. Its capacity is 220uF, rated voltage of 10V, rated ripple current and maximum ripple current of 157mA and 475mA. Its endurance and reliability are excellent.

The manufacturing process of Aluminum electrolytic capacitor is slightly different from that of ordinary electrolytic capacitors. The core of the alloy is made of aluminum, and is screened by a special activated powder film, then twisted into a cylinder shape, and then sealed by aluminum anode, filled with electrolyte as a medium to assist in the work. The surface is highlighted to make the capacitor look beautiful. Then cut the long cylinder into individual capacitors of the required size.

The working principle of aluminum electrolytic capacitor SN220M010ST is based on Faraday\'s law of electrolysis. The positive and negative electrodes are attached to both sides of an insulating film. The electric field in the film makes electrons and conduction ions move in different directions to form an electric current. Under the action of the electric field, the conduction ions and the electrodes will attract each other and form an electric double layer on the surface of the electrode. The capacitance of the capacitor is relates to the length, width, and thickness of the film, as well as the distance between the electrodes or the area of the film,for the same capacitor with the same dielectric material, the larger the area, the smaller the electric field applied to the film, and the greater the capacitance.

To summarize, SN220M10ST aluminum electrolytic capacitor can be applied in many areas, such as high-power DC-DC power supply modules, high-performance notebooks, medical instruments and automobile electronic equipment. It has excellent performance with a wide temperature range and a long lifetime, thanks to its special manufacturing process and working principle. It is reliable and worth purchasing.
