Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most common types of capacitors used due to their low cost, large capacitance range, and small size. They are primarily used in power management applications, and their working principle is based on the storage of charge on a thin film of aluminum oxide that has been deposited onto two conductive aluminum electrodes.

380LX272M100J452 Application Field

The 380LX272M100J452 aluminum electrolytic capacitor is one of the most commonly used designs due to its low cost and low ESR. It is primarily used in 10W to 15W audio applications, such as amplifiers, speakers and headphones. Additionally, it is suitable for use in Digital Audio Workstations (DAW), professional sound cards, broadcast systems, and other multimedia sound systems.

Working Principle

When voltage is applied to the capacitor, electrons are attracted to the negatively-charged cathode and are repelled by the positively-charged anode, creating an electric field between them. This electric field causes ions in the electrolyte to move and create an opposite electric field in the dielectric. This electric field increases the potential between the electrodes, which in turn stores charge on the thin film of aluminum oxide.

Pros and Cons

The main advantage of aluminum electrolytic capacitors is their low cost, large capacitance range, and small size. Additionally, they have a high volumetric efficiency, which means that they can store more charge in a given space than other capacitor types such as tantalum or ceramic. The main disadvantage of these capacitors is their relatively low voltage rating, which limits the amount of power that can be stored in a single device.

Conclusion

The 380LX272M100J452 aluminum electrolytic capacitor is one of the most commonly used designs due to its low cost, low ESR, and large capacitance range. It is primarily used in 10W to 15W audio applications and is suitable for use in Digital Audio Workstations (DAW), professional sound cards, broadcast systems, and other multimedia sound systems. It has the advantages of low cost, large capacitance range, and small size, but its low voltage rating limits the power it can store.
