Aluminum Electrolytic Capacitors - ALS70P513NF100: Application Field and Working Principle

Aluminum electrolytic capacitors belong to a category of passive electrical components that store energy in the electric field. They are used for various applications, ranging from signal-processing filters to power supplies. The ALS70P513NF100 is a special type of aluminum electrolytic capacitor that is commonly used for various applications. In this article, we will explain its application field and working principle.

Application Field

ALS70P513NF100 aluminum electrolytic capacitors are primarily used in power supply systems in industrial, medical, and military equipment. They are also used for various other general purpose applications, such as electronic filters and timing circuits. They offer a relatively high capacitance to size ratio, making them well suited for high-power applications.

Working Principle

Aluminum electrolytic capacitors rely on the dielectric properties of an electrically insulating thin film that is created between two aluminum electrodes. The electrodes of an aluminum electrolytic capacitor are made from a rolled foil of pure aluminum that is typically corrugated to increase surface area and the capacitance that can be stored. The thin film of an electrolytic capacitor separates the two aluminum electrodes and is created by the electrical reactions between the aluminum and the electrolyte. The electrolyte is usually either a wet chemical or a gel-like material that is applied to the aluminum foil and etched with a solution. This etching process forms an oxide layer on the aluminum foil that serves as an insulator, helping to increase the capacitance of the capacitor up to around ten times higher than non-electrolytic capacitors. For the ALS70P513NF100, the capacitance is rated at 70uF and the maximum operating voltage is 100V. The internal resistance of the aluminum electrolytic capacitors is relatively high, resulting in a characteristic device life limit. When the operating voltage exceeds the maximum rated voltage, the device life is significantly reduced.

Conclusion

In conclusion, the ALS70P513NF100 aluminum electrolytic capacitor is used for various power supply applications, such as industrial, medical, and military equipment. It features a relatively high capacitance to volume ratio, so it is well suited for high-power applications. The device life of an aluminum electrolytic capacitor is limited by its internal resistance, so it should not be operated at a voltage higher than its maximum rated voltage.
