The working principle of the APXA160ARA331MJC0S aluminum-polymer capacitor is based on the use of an aluminum inner layer separated by layers of layered polymer dielectric material. The aluminum layer functions as the anode, while the polymer dielectric layer acts as the cathode. The layers of the capacitor sandwich an electrolyte material. When an electrical current is applied, it induces an electrostatic charge in the polymer dielectric layers, which creates an electrostatic force field between the anode and cathode. This force field is responsible for storing charge, and is known as the capacitance effect.

The APXA160ARA331MJC0S is an all-around aluminum-polymer capacitor which can be used in a wide range of applications, offering reliable performance and power. Its many characteristics, such as high dielectric strength, low ESR, wide working temperature range, and various case sizes make it suitable for a range of applications. As such, it is an ideal component for a variety of electronic products which require reliable capacitance, low noise, and high temperature operation.
