Aluminum electrolytic capacitors are widely used in power electronics system. As one of the most important components for electronic devices, they have great influence on the system performance parameters such as frequency response, power dissipation, and charging speed. As an electrolytic capacitor, ALS70A472NF500 (hereafter referred to as ALS capacitors) is well-known for its excellent characteristics that guarantee its perfect performance in applications. This article is to reveal more details about its application and working principle.

ALS capacitors are used primarily in filter and regulator circuits, as well as high voltage rectifying circuits. They are also used in DC-DC converters and pulse transformers. Moreover, due to their high capacitance and high current capabilities, they are very suitable for use in power cycles, resonant circuits and some DC/AC converters. ALS capacitors are designed for use in various industrial, commercial, and automotive applications, as they have an excellent combination of reliability, low impedance, wide operating temperature range, high ripple current, low equivalent series resistance (ESR), and long life expectancy.

The working principle of ALS capacitors can be understood in four aspects. First, it uses non-polarized design which allows current to pass either way and thus increases its energy efficiency. Second, it adopts matte electrolyte structure to reduce its equivalent series resistance, making it suitable for use in resonant circuits. Third, it has a design of electrolyte separation, which increases its stability and reduces its capacitance-temperature coefficient. Fourth, its construction allows it to have a low and uniform dielectric temperature coefficient, which ensures a more stable performance of the capacitors.

The performance of ALS capacitors is mainly determined by its capacitance and ripple current capability. The capacitance of ALS capacitors lies in the range of 4.7 to 500F, and the maximum ripple current is up to 48000mA. Its capacitance and ripple current capability can be used together to develop further applications. For instance, its strong capacitance and current capability make it ideal for series– or parallel–mode resonant circuits in power electronics as well as filtering and high precision regulator circuits.

To conclude, ALS capacitors are reliable high voltage electrolytic capacitors with high capacitance and ripple current capability. Due to its non-polarized design, electrolyte separation, and low dielectric temperature coefficient, it provides performance characteristics well suited for operations in high frequency and high voltage applications. It also has an excellent combination of high reliability, low impedance, wide temperature range, and long life expectancy, making it suitable for multiple industrial, commercial, and automotive applications.
