Aluminum Electrolytic Capacitors

A capacitor is a device that stores and releases electric energy. There are various types of capacitors, with different working principles, applications, and performance characteristics. Among the many types of capacitors is the Aluminum Electrolytic Capacitor, represented by the code 381LX152M080H032. This article will discuss the application fields and working principles of aluminum electrolytic capacitors.

Application Field

Aluminum electrolytic capacitors are widely used in various applications, such as power supplies, motor drivers, automotive electronics, etc. Their wide application is due to their high capacitive value, high volumetric efficiency, stability, and cost-effectiveness. They feature a small size, and are resistant to temperature, load, and mechanical shock. Furthermore, they are useful in low-frequency, high-power circuits, where other capacitors fail to meet the requirements.

Working Principle

The working principle of aluminum electrolytic capacitors is based on the Faradaic reaction in an electrolytic solution. An anode is made of aluminum and immersed in an electrolyte solution, providing a surface for the Faradaic reaction. A cathode composed of a highly conducting material is placed in contact with the aluminum and electrolyte solution, forming the capacitive element. A separator is also present in between the anode and cathode and acts as an insulator. When a voltage is applied between anode and cathode, electric charges accumulate at both electrodes, creating a static field and leading to the storage of electrical energy.

Conclusion

Aluminum electrolytic capacitors, represented by the code 381LX152M080H032, are widely used in various applications because of their high capacitive value and volumetric efficiency. Their working principle is based on the Faradaic reaction in an electrolytic solution. Aluminum electrolytic capacitors provide a great solution to applications such as power supplies, motor drivers, and automotive electronics, in addition to low-frequency, high-power circuits.
