Introduction to Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is a type of capacitor that uses an aluminum foil that is oxidized to form an insulator layer, as a dielectric material. It utilizes an electrolyte soaked into the layer of oxide to increase the electrical conductivity of the material. Aluminum electrolytic capacitors can come in both axial and radial designs, offering power densities up to 30,000 times more than ceramic capacitors. This type of component is commonly used in power supplies, automatic controls, and switching circuits.

UCD1V471MCL6GS Application Field and Working Principle

The UCD1V471MCL6GS is an aluminum electrolytic capacitor produced by Nichicon Corporation. It has a rated voltage of 4V and a capacitance of 47μF, with 6 terminals for electrical connection. This capacitor is designed to have low-impedance and long life, making it suitable for wide range of applications. These include battery operated devices such as remote controls, cell phones, and laptops, as well as applications that require low-leakage, typically developing equipment.

When in use, the aluminum electrolytic capacitor acts as a device that stores energy. This is done by having an aluminum foil plate which acts as the anode and an electrolyte layer as the cathode, separating them by a thin oxide layer. The electrolyte layer can be either liquid or solid. When a voltage is applied across the terminals of the capacitor, a potential difference is formed between the anode and the cathode. This creates an electric field between the anode and the cathode, resulting in a charge stored and a capacitance present.

When an alternating voltage is applied across the capacitor, the electrons on the anode move to the cathode in response to the field, while the positive ions move from the cathode to the anode. This causes the stored energy to be decreased until the voltage drops below the applied voltage. When the voltage drops below a certain level, the electrons are drawn back to the anode, replenishing the energy stored in the capacitor. This process continues the charge/discharge cycle, while dissipating small amounts of heat.

Conclusion

The aluminum electrolytic capacitor is a powerful and reliable form of electronic component, highly suited for various applications. It provides a higher power density and longer-life than ceramic capacitors, making it a suitable choice for power supplies, circuit controls, and switching systems. The UCD1V471MCL6GS is an example of a high-performance aluminum electrolytic capacitor produced by Nichicon, offering low-impedance and long-life. It works by storing energy through the charge/discharge cycle of electrons, and is optimized for use in battery operated devices and low-leakage applications.
