Aluminum electrolytic capacitors, or simply electrolytic capacitors, are electrochemical capacitors that use an aluminum oxide layer as the dielectric material. This makes them a special type of capacitor, as they offer much higher capacitance values than other types of capacitors. This makes them ideal for applications requiring high capacitance levels, such as filtering, signal conditioning, and storage. The ALS81G123NT400 is a type of aluminum electrolytic capacitor and is designed for applications that require a high capacitance level.

The ALS81G123NT400 capacitor is a subcategory of aluminum electrolytic capacitors. It is designed to provide both high capacitance and low ESR (Equivalent Series Resistance). This makes it an excellent choice for applications requiring a high capacitance level with a minimal amount of power loss. The capacitor features a cylindrical aluminum casing with epoxy resin end caps. It has both a negative and a positive terminal, with a voltage rating of 50 VDC. The rated capacitance is also high, at 1200 μF.

The working principle of the ALS81G123NT400 capacitor is similar to other aluminum electrolytic capacitors. The capacitor is made up of two aluminum foils, each separated from each other by a thin dielectric oxide layer. When a voltage is applied across the capacitor, the oxide layer prevents current from flowing directly between the two aluminum foils, creating an effective electric field. This electric field induces electrons to move through the oxide layer, creating a charge between the two aluminum foils. This charge is the capacitance.

The ALS81G123NT400 capacitor is ideally suited for high current/high voltage applications, such as power supply filter circuits, switching circuits, that require a high capacitance level and low ESR. The capacitor also has a long life expectancy, making it an excellent choice for high reliability applications. The capacitor is also commonly used in audio-video equipment, such as amplifiers, in order to provide filtering and smoothing as well as power supply decoupling. Other applications include high frequency snubbers, power conversion, and backup power supplies.

In summary, the ALS81G123NT400 is a type of aluminum electrolytic capacitor. It is designed to provide both high capacitance and low ESR for applications requiring a high capacitance level with minimal power loss. The capacitor features a cylindrical aluminum casing with epoxy resin end caps and a voltage rating of 50 VDC. The working principle of the capacitor is similar to other aluminum electrolytic capacitors, with two aluminum foils separated by a dielectric oxide layer that creates a charge when a voltage is applied across the capacitor. The capacitor is ideal for high current/high voltage applications, such as power supply filter circuits, and has a long life expectancy for high reliability applications.
