Aluminum Electrolytic Capacitors and their Application Field and Working PrincipleAluminum electrolytic capacitors are a type of capacitor that uses an electrolytic process to store energy in an electric field. Unlike ceramic capacitors, aluminum electrolytic capacitors operate in a reverse-polarized field, and have a higher capacity and longer life than ceramic capacitors. They are highly versatile and can be used in many applications, such as: 1. High-voltage, High-current applications; 2. Power supply filters and power line bypass filters;3. Voltage regulation;4. AC motor drive circuits;5. Radio frequency and audio frequency power applications.The most common aluminum electrolytic capacitor available is the UVZ2C221MHH. It has a maximum voltage of 25V, a capacitance of 220uF, and a maximum operating temperature of 100°C. The package dimensions are 11.3 x 13.3mm, and the weight is 1.5g.This type of capacitor is useful for applications where extra capacitance is needed for short-term peak currents. Its wide temperature range makes it suitable for various difficult environmental requirements. Furthermore, it has an inherent self-healing characteristic, where it can recover from damage caused by binding, vibration or drops.The working principle of an aluminum electrolytic capacitor is relatively simple. It consists of a cathode foil and an anode foil that are separated by an electrolyte layer. On the anode foil is a thin layer of insulating oxide that serves as the dielectric. When a voltage is applied across the two foil electrodes, an electric field is created and positive ions in the electrolyte are attracted to the anode. These ions carry electric charge and are stored by accumulating near the anode, thus creating a capacitor. This charge builds up as the capacitor is charged and stored as electrical energy.The capacitance of the aluminum electrolytic capacitor depends on a number of factors, such as the area of the aluminum foil, the distance between the plates, and the properties of the electrolyte. The capacitance also changes over time due to electrolyte leakage, electrolyte evaporation and thermal drift. As a result, these capacitors are generally rated for a maximum temperature and voltage, and should be used within their specified limits.Overall, aluminum electrolytic capacitors are a reliable and versatile type of capacitor that can be used for a variety of applications. They offer good performance at high voltage and low impedance, and are capable of handling transient currents. Although they have a limited life and can be prone to other problems, they are still a viable option for many different applications.
