Aluminum Electrolytic Capacitors Aluminum electrolytic capacitors, which are also referred to as polarized capacitors, are one of the most common types of capacitors available today. They consist of two aluminum plates, separated by a dielectric layer of oxide film. One plate is the anode and the other is the cathode. The anode is a thin aluminum foil and the cathode is a larger, thick aluminum foil. A conductive electrolyte, usually composed of an organic solvent and a variety of dissolved ions, bridges the anode and the cathode.The capacitors have several advantages, such as low cost, high capacitance values, good stability, and easy installation. They can also be connected in series or parallel with other components, making them very versatile. Because of these advantages, they are widely used in various applications, such as power supplies, consumer electronics, automotive applications, and industrial controls.The UVK1V221MPD application field and working principle are part of the aluminum electrolytic capacitors family. The UVK1V221MPD is a radial leaded, two-terminal aluminum electrolytic capacitor. It is mainly used for general purpose applications in auto, consumer, communication and power electronics, such as filtering, buffer, surge and anti-EMI. The UVK1V221MPD is designed with superior reliability, high ripple current capacity, low equivalent series resistance (ESR), and long life.The working principle of the UVK1V221MPD is based on the capacitor’s construction. As mentioned before, the capacitors consist of two aluminum plates, separated by a dielectric layer of oxide film. When a DC voltage is applied across the two plates, a reaction occurs between the oxide film and the electrolyte. This reaction produces positive and negative charges on each aluminum plate, thus creating a capacitance between the plates. The capacitance of the capacitor is determined by the size, thickness, shape, and the dielectric constant of the oxide film. As the applied voltage increases, the charges on the plates increase, leading to an increase in the capacitance. The charges on the plates also decrease when the applied voltage is decreased, leading to a decrease in the capacitance.The UVK1V221MPD also offers several other features, such as low ESR, high current and ripple current capacity, excellent de-rating capability, and low power loss. In addition, the capacitors are designed for higher reliability and long-term performance. Furthermore, they are UL and CSA approved, making them safe to use in a variety of applications.Overall, the UVK1V221MPD is a very versatile and cost-effective capacitor that can be used in general purpose applications, such as filtering, buffer, surge and anti-EMI. It offers superior reliability, high ripple current capacity, low equivalent series resistance (ESR), and long life. In addition, its UL and CSA approval makes it safe to use in a variety of applications.
