Aluminum electrolytic capacitors, or aluminium electrolytic capacitors, are polarized electrolytic capacitors. It consists of two electrodes, separated by an electrolyte, with a positive plate made of aluminum foil separated by a layer of insulating aluminum oxide. The capacitance of the assembly is determined by the effective area of the anode and its distance from the cathode. It stores an electric charge that can provide a controlled amount of current to circuits over a period of time.

UCB0J220MCL1GS is an aluminum electrolytic capacitor with high performance and a wide range of application. It is a low-profile, RoHS compliant aluminum electrolytic capacitor with long service life and excellent capacitance stability. With a maximum voltage rating of 350V, excellent insulation performance, and low equivalent series resistance, UCB0J220MCL1GS is suitable for various fields.

It is most commonly used in various communication systems, such as radio and television receivers, and wire and cable transmission lines. Other than that, it also has significant importance as a standard component in AC and DC power supplies, switching power supplies, inverters, motor drives, and in electronic instrumentation where an adjustable load is requested. It can also be used to filter high frequency signals, compensate power output, and used for signal attenuation.

Its working principle is based on the formation of a non-conductive layer of aluminum oxide on its anode, which is created and maintained by the applied voltage. When the applied voltage is greater than the voltage of the aluminum oxide layer, a current flows through the capacitor, depositing electrons on the surface of the aluminum oxide, until potassium ions reach equilibrium with the resulting oxygen ions. This forms an electrical double layer, allowing the aluminum oxide layer to conduct electricity.

The electrostatic effect of the oxide layer is proportional to the applied voltage, which increases the capacitance of the device. The electrolytic capacitor thus works as a kind of controlled voltage source, allowing an uncontrolled voltage source to be used as a regulated voltage source. This means that it is suitable for a wide range of AC and DC applications, such as re-clocking, pulse-shaping, and power conditioning.

UCB0J220MCL1GS, as mentioned before, is an aluminum electrolytic capacitor with many application fields. It is suitable for various communication systems, power supply, switching power supplies, inverters, motor drives, and electronic instrumentation that requests an adjustable load. Based on its working principle, it can be used to filter high frequency signals, compensate power output, and used for signal attenuation.
