Aluminum Electrolytic Capacitors: EKXJ451ELL150MJ25S Application Field and Working PrincipleAluminum electrolytic capacitors (also known as aluminum electrolytic capacitors or aluminum electrolytic capacitors) are one of the most widely used types of capacitors. Nowadays, the output current of aluminum electrolytic capacitors in power switching circuits of communication and industrial power applications is rapidly increasing. Capacitors are used to store electric charges on their electrodes. They are also used to limit the rate of voltage rise in a circuit, and use the energy of the spike to drive another circuit. An aluminum electrolytic capacitor consists of two metal electrodes, electrodes and electrolyte. The capacitor is composed of an aluminum foil pattern and an activated oxide film, which is made by anodizing aluminum foil in acid electrolyte. Due to their small capacitance and dielectric loss, electrolytic capacitors can be used for high-frequency applications.The most common application field of aluminum electrolytic capacitors is as a purpose-specific energy storage element, such as in energy storage modules and voltage regulating circuits. The voltage regulating circuit is the primary application field of aluminum electrolytic capacitors. These capacitors provide a smooth current output at varying input frequencies and are typically used for power supplies, switch mode power supplies (SMPS), and automotive power systems. They are also suitable for use with electric and gas turbine alternators, where they smooth out the ripple current to provide a steady input. Moreover, aluminum electrolytic capacitors have extended their application fields into power filtering in audio and radio frequency, especially in power amplifiers. The capacitors are also used in ripple noise, high current charging or discharging control, and over-voltage protection circuits. In automotive electronics, aluminum electrolytic capacitors are used in electronic ABS and traction control systems.The working principle of an aluminum electrolytic capacitor is based on the electrical properties of aluminum oxide. Aluminum oxide films form a reliable dielectric between the electrodes, which is electrically insulating and does not permit electrical charges to pass between them. The capacitance is determined by the area of the aluminum oxide film and its thickness. The capacitance of an aluminum electrolytic capacitor is inversely proportional to itsworking voltage, meaning that as the voltage increases, the capacitance decreases. The capacitance of an aluminum electrolytic capacitor also varies with temperature and frequency, and may be affected by electrolyte type, mode of operation, and temperature coefficient. Aluminum electrolytic capacitors require a negative polarity voltage to charge their dielectric film. To prevent potential damage and dndissipation by excessive current flow, it is important to pay attention to the limitations of its maximum operating voltage and temperature.In conclusion, aluminum electrolytic capacitors are used to store electric charges, limit the rate of voltage rise in a circuit, and use the energy of the spike to drive another circuit. The EKXJ451ELL150MJ25S application field includes purposes such as energy storage modules, voltage regulating circuits, power filtering, ripple noise, high current charging or discharging control, and over-voltage protection circuits. Its working principle is based on the electrical properties of aluminum oxide, and the capacitance is determined by the area of the aluminum oxide film and its thickness.
