This type of capacitor is especially useful in applications such as high frequency filtering, pulse applications, and noise reduction. Additionally, due to their construction and design, aluminum electrolytic capacitors are also exceptionally robust and can handle high operating temperature compared to other types of capacitors. Moreover, they can also be used in applications where a low power dissipation is required, such as with personal computer motherboards and other kinds of digital electronics circuits.

Aluminum electrolytic capacitors work by using an electrochemical construction which involves the use of two aluminum foils along with a paper separator soaked in an electrolyte. The anode foil is etched to increase the surface area and therefore gaining a higher capacitance. This technology allows for even greater capacitance values compared to other types of capacitors, while ensuring excellent stability, high reliability, and a long lifespan.

The dielectric layer in aluminum electrolytic capacitors is a solid oxide formed on the anode by electrolysis, which serves to separate the two conductive electrodes from each other. The layer is constructively made by reactivating its original anode material, providing a high electrochemical stability at the same time as a low leakage current.

Temperature cycling capability of aluminum electrolytic capacitors depends on the electrolyte used, but most of them feature a working temperature range between -40°C and +85°C. In addition, they are also able to handle a large amount of mechanical vibration, making them suitable for use in many electrical equipment chassis.
