Aluminum Electrolytic CapacitorsAluminum electrolytic capacitors are a type of electrolytic capacitor where the electrodes consist of aluminum foil. It is a non-polarized capacitor type, meaning that there is no polarity throughout the capacitor. Unlike other types of capacitors such as tantalum electrolytic capacitors, aluminum electrolytic capacitors are easily available in large values and very small sizes. These characteristics make them a great choice for use in electronic circuits, such as power supplies, where large values of capacitance and small size are both required.The UVK2G2R2MPD application field and working principle of an aluminum electrolytic capacitor are quite simple and straightforward. At the most basic level, an aluminum electrolytic capacitor is a mechanical device that stores electrical energy in the form of a voltage between two aluminum metal plates. When voltage is applied to the two plates, electrical charge will flow through the capacitor, causing the two plates to become polarized. This polarization creates a dielectric field which stores the charge in the capacitor.The electric charge stored in an aluminum electrolytic capacitor will remain stored until a certain point is reached. As the voltage applied to the capacitor increases, the capacitance will decrease and the max voltage will be reached at which the charge can no longer be stored. This is known as the rated voltage of the capacitor. Depending on the type of aluminum electrolytic capacitor, the rated voltage can be anywhere from 6 to 400 volts.The other important component in an aluminum electrolytic capacitor is the electrolyte. The electrolyte is liquid or gaseous and helps to keep the plates polarized so that the charge stored in the capacitor does not leak out. The electrolyte also affects the characteristics of the capacitor such as the ripple current, leakage current, and the dielectric absorption.An aluminum electrolytic capacitor is typically used in applications where high capacitance values and small sizes are both required. Applications include power supplies, voltage transient suppression, noise filtering, and in frequency-dependent filters. In addition, these capacitors are also used in switch mode power supplies (SMPS) as well as in audio frequency meters, electric oscillators, and in phase locked loop circuits.The main advantages of using an aluminum electrolytic capacitor are a large capacitance in a small size, the ability to handle high voltage levels without risk of breakdown, and an extended product life. The downside of these capacitors is that they tend to suffer from aging due to the effects of electrolyte evaporation, temperature degradation, humidity, and vibration.Overall, aluminum electrolytic capacitors offer a great combination of large capacitance, reliability, and small size. They are an essential component for many electronic circuits, and with proper maintenance and care can provide a long-lasting product that will provide reliable performance.
