Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are made up of multiple layers of oxygen-free aluminum foil that are rolled up and encased in a pressure-resistant coated container. The aluminum foil is then coated internally with a dielectric layer of electrolyte, and two electrical connections, positive and negative, are attached to the container to provide a power source. These capacitors are used to store electrical energy temporarily, making them well-suited for a variety of electrical applications.The UUA1V221MNL1GS aluminum electrolytic capacitor is a polarized capacitor with a cylindrical shape and a rated maximum voltage of 35 volts. It is designed for use in a wide range of applications such as digital circuits, inverters, UPSs, and audio equipment. The capacitor has a wide temperature range of -55°C to +125°C, making it suitable for use in extreme temperature conditions. It has a rated capacitance of 220uF, rated ripple current of 3.0mA and a long lifetime of 1000 hours at the rated temperature.The working principle of an aluminum electrolytic capacitor is based on Faraday\'s Law of Electrolysis, which states that the voltage across a capacitor must be related to the area of surface and the amount of charge that has been transferred on it. The aluminum electrolytic capacitor contains a positive and a negative electrode, located in two different regions inside the capacitor, separated by a dielectric material which contains aluminum oxide. When a potential difference is applied across the capacitor, current flows from the positive to the negative electrode. This causes charged particles of the electrolyte to migrate from the negative to the positive electrode, attracted by the higher potential. The electrical charge is then stored as an electrical field in the dielectric material, generated between the two electrodes. As the charge accumulates, it distorts the shape of the aluminum oxide crystal lattice, resulting in a larger capacitance value. When the potential difference is removed, the charge remains stored in the capacitor until it is discharged again. The amount of charge stored in an aluminum electrolytic capacitor is determined by its rated voltage and capacitance values, and the temperature of the environment in which it is used. The UUA1V221MNL1GS aluminum electrolytic capacitor can be used in a wide range of applications where capacitors with larger capacitance and higher voltage ratings are not suitable. These applications include analog and digital circuits, inverters, UPSs, and audio equipment. The capacitor\'s capacitance, voltage, and temperature ratings make it the perfect choice for applications where a high degree of energy storage is needed under extreme temperature conditions.Aluminum electrolytic capacitors are widely used in the electronics industry, due to their low cost, long lifetime, and high performance. The UUA1V221MNL1GS aluminum electrolytic capacitor is a reliable and cost-effective option for a wide variety of electrical applications. It is the perfect choice for designers who need capacitors with excellent performance under extreme temperature conditions.
