Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most frequently used capacitors for power supply filtering and energy back-up in applications such as industrial, automotive and aerospace. They have several characteristics that make them unique from other types of capacitors. The main difference between aluminum electrolytic capacitors and other capacitors is the type of capacitors which are made of aluminum oxide film. The oxide film provides an extremely high capacitance per unit volume compared to other types of capacitors. Additionally, the capacitance of aluminum electrolytic capacitors is temperature and voltage dependent, which is beneficial in many applications.The 450C871M450BH8 aluminum electrolytic capacitor is designed to meet demanding power supply filtering and energy back-up requirements. It is a powerful solution for low ESR and long service life applications. It has a maximum rated voltage of 450V and a 60,000-hour load rotation cycle rating. It features a high ripple current capacity and superior mechanical strength, allowing it to be used in intensive environments.The 450C871M450BH8 aluminum electrolytic capacitor is ideal for use in telecom power systems, traction power grid, UPS, generators and home lighting systems. These capacitors provide superior reliability in high-current high-temperature environments due to their superior thermal stability and design.The working principle of an aluminum electrolytic capacitor is quite simple. An electrolyte is sandwiched between two aluminum plates called electrodes. A build-up of electric charge occurs between the two plates and an electric field is created in the gap between the plates. This electric field gives rise to a capacitance between the two plates, resulting in a storage of energy. This energy is stored in the capacitor and can be released when the conditions are right, such as when the load is switched off. The capacitance of an aluminum electrolytic capacitor can be determined by several factors, including the size of the aluminum foil plates, the thickness of the oxide layer, the temperature and the voltage, to name a few. The maximum rated voltage of the capacitor is one of the most important factors as it directly affects the capacitance of the capacitor. The capacitance also increases when the temperature is increased, but this is usually not recommended as it leads to decreased stability and reliability of the capacitor.In summary, the 450C871M450BH8 aluminum electrolytic capacitor is an excellent choice for applications requiring high capacitance, high reliability and stability. It provides superior performance in high temperature, high ESR environments due to its aluminum oxide construction and its temperature and voltage-dependent characteristics. The working principle involves the formation of an electric field between two aluminum plates that results in a buildup of electrical charge and a capacitance between the plates.
