Aluminum electrolytic capacitors are widely used in various electronic devices. They are divided into non-polarized capacitors and polarized capacitors. Among them, LLS2C681MELA aluminum electrolytic capacitor is a low-leakage, high-ripple current, long life type non-polarized electrolytic capacitor.The application field of LLS2C681MELA aluminum electrolytic capacitors is very wide. They are mainly used in the fields of power cord and power supply, display device, LED drive, communication, computer and automobile. They are applicable to high frequency electronic communication equipment, high power convertor filters in aviation, navigation and rail transportation, etc.The working principle of LLS2C681MELA aluminum electrolytic capacitor is humidification and dehumidification. It is a capacitor composed of two aluminum foils separated by an electrolyte. It is sealed in an insulating can, and the two foil ends of the aluminum foil are connected to the two terminals of the capacitor. When a certain voltage is externally applied to the capacitor, an electric field is formed in the electrolyte, and an electric double layer is formed on the surface of the two aluminum foils. Thus, two electric fields are formed on both sides of the electrolyte, and the dielectric value of the electrolyte is increased, resulting in capacitance. At the same time, the electrolyte and its electrolytic solution are polarizable and deformable, and the surface of the two aluminum foils also have an effect of increasing the dielectric value. Therefore, such capacitors can provide higher capacitance at the same size than other types of capacitors.The leakage current of LLS2C681MELA aluminum electrolytic capacitors is much smaller than that of other types due to the layer formed on the aluminum foil. Moreover, its ripple current capacity is very high. The life of the power capacitor is mainly determined by its internal temperature, which mainly depends on the air permeability characteristics of the insulating adhesive lining the capacitor. The inner package is vacuum-sealed and colored with red lead powder to improve airtightness, so that internal temperature rise is effectively prevented. In addition, the life of electrolytic capacitor is also very long, and it will not reduce due to high temperature, so it is also very good in terms of safety and reliability.In summary, LLS2C681MELA aluminum electrolytic capacitor is a low-leakage, high-ripple current, long life type non-polarized electrolytic capacitor, which is widely used in various electronic devices. Its application field is very wide, and it has excellent performance in safety, reliability and long life. Therefore, it can be used in many fields, such as power cord and power supply, display device, LED drive, communication, computer and automobile.
