Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are the most widely used capacitors for edging applications and voltage filtering. These capacitors use the phenomenon of an electric double layer at the interface between a dielectric that is an oxide film and an electrolyte, which is usually an aqueous solution of an alkaline or acidic compound. The capacitors are widely used in noise suppression, voltage filtering, pulsed power operations, and other electrical engineering applications.

380LX271M400A022 application field and working principle

The 380LX271M400A022 aluminum electrolytic capacitor is a polarized, screw-type safety capacitor with an operating temperature range of -55°C to +125°C. The capacitor is suitable for general electronic applications such as voltage filtering and power supplies. It is also used in many types of noise suppression applications in electrical systems.

The 380LX271M400A022 capacitor consists of an aluminum oxide dielectric layer between a pair of electrodes. This Oxide layer is formed on the surface of the aluminum foil by anodization in an electrolyte solution. The anode and cathode ends of the capacitor are connected to the two terminals of the power supply. When voltage is applied to the terminals, a positive charge is developed on the aluminum foil. This positive charge attracts negative ions from the electrolyte solution and forms an electric double layer at the interface of the aluminum oxide layer and the electrolyte.

This electric double layer acts as a dielectric and creates a capacitance between the electrodes. The capacitance produced depends on the value of the voltage applied across the two terminals of the power supply, the thickness of the oxide layer, the type of electrolyte solution used, and the area of the aluminum foil. The higher the voltage, the larger the capacitance.

The 380LX271M400A022 aluminum electrolytic capacitor is designed to provide a high capacitance level and to be low ripple and low noise. This makes it suitable for a wide variety of noise suppression and voltage filtering applications, such as in microwave ovens, power supplies, TVs and radios, and other consumer electronic devices.

The 380LX271M400A022 aluminum electrolytic capacitor is a robust capacitor that can handle voltage up to 500V and temperature up to 125°C. It is also extremely reliable and has a long service life. The capacitor is available in various sizes and capacitance values, allowing users to select the most suitable model for their application.
