They are mainly used as filtering, decoupling and bypass/coupling capacitors.

Working Principle

Aluminum - polymer capacitors are electric double-layer capacitors that use thin aluminum foils coated with an insulating layer of polymer. This type of capacitor contains two electrodes which are separated by an electrolytic material such as an aluminum oxide or pseudocapacitor type film. When a voltage is applied, the electrolytic material serves as an ionic bridge between the two electrodes, allowing the capacitor to store electrical energy. The dielectric strength of the capacitor is determined by the thickness of the polymer layer and the quality of the electrodes.

When the capacitor is connected to a power source, electric charge flows across the aluminum foils and the electrolytic material. As the electrons accumulate on the electrodes, the electric field between them increases, which causes them to repel each other. This repelling action creates a capacitance that stores the electrical energy.

Advantages of Aluminum - Polymer Capacitors

Aluminum - polymer capacitors are often preferred over traditional aluminum electrolytic capacitors because they offer several advantages such as wide operating temperature range,low ESR (equivalent series resistance) and high current handling capability. They are also lightweight, small, and have a long life expectancy.

Aluminum - polymer capacitors are highly reliable and have a lower leakage current compared to other types of capacitors. Therefore, they are often used in applications where long-term performance is important such as automotive and HVAC applications.
