Aluminum Electrolytic Capacitors

KY16VB272M12X30LL

Electrolytic capacitors, which are also called electrolytic super capacitors, are special components that have two electrodes and an electrolyte between them. They are widely used as energy storage devices for inverters, power supplies, motor protection and other applications. One of the most popular models is KY16VB272M12X30LL, which is a reliable and cost-effective aluminum electrolytic capacitor. In this article we will look at the application field and working principle of this capacitor.

Application Field

The KY16VB272M12X30LL capacitor is primarily used in power supplies, motor protection and other energy storage applications where high energy density, high reliability, and wide temperature range are important. It is one of the most common models used and is suitable for both low- and high-voltage applications. It is also an excellent choice for power systems due to its good capacitance-voltage coefficient, low ESR, and low inductance.

Working Principle

Aluminum electrolytic capacitors are the most popular type of electrolytic capacitor. They work through the combination of an electrolyte solution and a porous aluminum oxide sheet, which serves as the dielectric medium. The porous layer of aluminum oxide is formed when current is passed through the electrolyte solution. The current produces a thin layer of oxide on the aluminum substrate, which acts like an insulator, preventing current from passing through the electrolyte solution.The pores in the aluminum oxide layer act as a layer of insulation, allowing a charge to accumulate on its surface. One electrode of the capacitor is connected to the aluminum layer and the other to the surrounding electrolyte. When a voltage is applied to the electrodes, a current will flow between them. The current creates a static charge on the oxide layer, which serves as the capacitor\'s charge storage.The amount of charge that can be stored in the capacitor is proportional to its capacitance (or C-value). The KY16VB272M12X30LL capacitor has a C-value of 272μF, which makes it suitable for applications where large amounts of energy storage is needed.The other important factor to consider when evaluating capacitors is the ESR, which stands for equivalent series resistance. This is the electrical resistance of the capacitor which affects its response to changes in temperature. The KY16VB272M12X30LL capacitor has a low ESR, which makes it suitable for applications where high reliability is required.

Conclusion

The KY16VB272M12X30LL capacitor is a cost-effective and reliable aluminum electrolytic capacitor. It is suitable for low- and high-voltage applications, such as power supplies, motor protection, and other energy storage applications where high energy density, high reliability, and wide temperature range are important. The capacitor also has a high C-value of 272μF and a low ESR, which makes it suitable for applications where high reliability is required.
