With its robust construction, aluminum-polymer capacitors are also ideal for DC link circuits, where bulk capacitance and long-term reliability are required.

Working Principle

Aluminum-polymer capacitors are based on the basic capacitor structure, which consists of two conducting plates separated by an insulating material. In the aluminum-polymer construction, the dielectric material is a polymer housed between two conductive aluminum layers. This construction increases the surface area of the capacitor, allowing for higher capacitance values. The unique benefit of this type of capacitor is that the electrolytic dielectric is not exposed to external environmental factors, thus avoiding any issues with ageing. The dielectric material also increases the basic capacitance levels, enhances the capacitance stability, and ensures that the leakage current is lower than traditional aluminum electrolytic capacitors.
