Polymer Capacitor are capacitors that use a polymer dielectric as its primary component rather than ceramic or metal. They are a particular class of electrical part designed to hold electric charges. Compared to other kinds, such aluminum or tantalum electrolytic capacitors, they have a number of benefits. Traditional tantalum or aluminum caps rust, while polymer capacitor do not, and they can even be utilized in harsh weather conditions. They provide higher performance and dependability, which is why many automakers have embraced them as the top option for their automotive electrical systems, such as those found in hybrid electric vehicles (HEVs).

To reduce power noise, solid polymer caps can be utilized to smooth out the voltage going from a power source to a delicate circuit. If the working voltage is low enough, they can simply replace conventional electrolytic capacitors in certain applications. The cathode of a polymer-type aluminum electrolytic capacitor is composed of conductive polymer, while the anode is made of aluminum foil. Tantalum metal serves as the cathode and conductive polymer serves as the anode in a polymer-type tantalum electrolytic capacitor.
