Aluminum electrolytic capacitors are widely used in most electronic circuits, such as power supplies, digital signal processing systems, and DC/DC converters. Among the variety of aluminum electrolytic capacitors available, the 108CKR063M series stands out for its high reliability, long life, and high current transfer capability. In this article, we will explore the application fields and the working principle behind the 108CKR063M series.

Application fields

The 108CKR063M series of aluminum electrolytic capacitors come in a range of values, making them a versatile choice for a variety of applications. They are used for smoothing and filtering, voltage boosting, energy storage, high current pulse applications, and ripple current reduction. For added applications, they can also be used to condition power supply operations, avoiding large inrush currents and preventing arcing.

In particular, these capacitors are well-suited for industrial applications, such as welding machine or motor drive applications. They are used in conjunction with power converters, offering stable operation even in extreme temperatures, and protecting the equipment from failures due to short circuits.

Working Principle

Aluminum electrolytic capacitors are made up of two flat layers of aluminum that are separated by a thin porous paper made of a special electrolyte. The next layer is usually a thin plastic film which serves to insulate the entire construction. An electrical current is then applied between the two plates and it results in a charge buildup on them. This charge is usually stored as a negative charge on one plate and a positive charge on the other.

Because of the negative and positive charges, these capacitors act as a sort of “conduit” for electrical current to flow between them, allowing them to be used for power filtering and AC blocking applications. They are also ideal for high frequency applications, as their size is relatively small and they have a high amount of capacitive reactance, allowing them to maintain a consistent load.

To extend aluminum electrolytic capacitors’ life span, they usually include a series of protective mechanisms. One of these mechanisms includes a safety vent where liquid electrolyte is safely released to prevent the capacitor from exploding or igniting due to overheating. This safety vent is often located near the base of the capacitor and it is specifically designed to open when the temperature of the capacitor exceeds a certain level.

Conclusion

The 108CKR063M series of aluminum electrolytic capacitors are used in a variety of applications where high reliability, long life, and high current transfer capability are required, such as welding machines or motor drives. They are formed of two flat aluminum layers, a thin porous paper of special electrolyte, and a thin plastic film which serves as an insulator. Through their negative and positive charges, they act as a “conduit” for electric current to flow between them, allowing them to be used for power filtering and AC blocking applications. Finally, the 108CKR063M series also includes several protective mechanisms, including a safety vent which opens up when the capacitor gets too hot.
