Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is an electronic component that utilizes an electrolyte composed of liquid or gel containing microscopic particles suspended in a solvent. These particles are suspended in the electrolyte and use an electrical current to form an adjustable layer of insulation that is used as a capacitor in electronic circuits. Aluminum electrolytic capacitors are typically used in applications requiring high current or large capacitance values and can often be found in power supplies, motor controllers, amplifiers, and other devices that require low reactance and low impedance.

380LX121M500K022 application field and working principle

Aluminum electrolytic capacitors are commonly used in power electronics applications due to their high capacity, low ESR, and long life. The 380LX121M500K022 is an aluminum electrolytic capacitor with a rated voltage of 120V and a capacitance of 500µF. The 380LX121M500K022 has a maximum ripple current of 15A and a long life rating of 1,000 hours. In addition, the 380LX121M500K022 has a temperature rating of -55°C to +105°C, making it suitable for use in a wide range of applications.

The working principle of an aluminum electrolytic capacitor is based on the behavior of certain metallic oxides when an electric field is applied to them. These oxides are able to store electrical charge in the form of a separation of positive and negative ions. The positive ions are stored on the surface of the oxide while the negative ions remain in the electrolyte. When the voltage across the capacitor is raised, the internal electrical field increases, causing the oxide to polarize and allow the ions to move. This movement of ions creates a charge separation which allows the capacitance to increase.

The advantages of aluminum electrolytic capacitors over other types of capacitors include their low cost, low equivalent series resistance (ESR), and high capacitance values. In addition, aluminum electrolytic capacitors have a long life and are relatively easy to install.
