Aluminum Electrolytic Capacitors: 400VXG270MEFC35X30 Application Field and Working Principle

Aluminum electrolytic capacitors are electronic components commonly used in various electrical and electronic circuits. It is made by winding an anode aluminum foil around a cylindrical insulator, then a separator moistened by electrolytic solution and a cathode foil is placed on it. The capacitor is sealed with a special sealing caps. Such an aluminum electrolytic capacitor is mainly composed of a cylinder, an anode, a dielectric, a separator and a cathode, among which the anode aluminum foil winding for low resistance is also called the “wet electrolyte aluminum electrolytic capacitor”. The specific device of the aluminum electrolytic capacitor is to store electrical energy between two conducting electrodes separated by electrolyte medium. When an external alternating current flows through the aluminum electrolytic capacitor, an electrostatic field is formed in the electrolyte medium. The electric energy stored in the medium is called capacitor electric energy. The ratio of the stored capacitance electric energy to the applied electric potential is called capacitance. When the capacitor voltage increases, the dielectric strength of the capacitor also increases, which is called the self-healing function of the aluminum electrolytic capacitor. Therefore, the applications of aluminum electrolytic capacitors involve topics such as smoothing, filtering, transient voltage suppression, frequency selective boosting and reacting circuit. The working principle of aluminum electrolytic capacitors is based on the electrochemical principle. Generally speaking, aluminum electrolytic capacitors have electrochemical resistance, and electrolytic capacitors are widely used in various power frequency applications due to their large capacity. Under certain conditions, they can also be used as capacitors or snubbers in high frequency signal circuits; with its large capacity and self-healing features, aluminum electrolytic capacitors are used for filtering, buffering, viscous damping, rectification and energy storage. The 400VXG270MEFC35X30 aluminum electrolytic capacitor uses an electric double layer capacitor technology to achieve large capacity and high voltage capability. This type of capacitor is suitable for high ripple current, high surge impulse voltage and high ambient temperature operation. It also has low ESR, long life, wide operating temperature, low leakage current, symmetrical capacitance and humidity immunity, making it the perfect choice for motor controls, UPS and telecom power, etc. When used, the voltage applied should not exceed the rated voltage; overtemperature may also reduce the life of the capacitor or cause it to burst.In summary, the 400VXG270MEFC35X30 aluminum electrolytic capacitor is a kind of electric double layer capacitor with large capacity and high voltage capability. It is suitable for high ripple current, high surge impulse voltage and high ambient temperature operation. It has low ESR, long life, wide operating temperature, low leakage current, symmetrical capacitance and humidity immunity. It finds applications in motor controls, UPS and telecoms power, etc.
