Aluminum-Polymer Capacitors are a type of rechargeable capacitor with a wide variety of application fields, including energy storage, power conditioning, and power delivery. These capacitors are suitable for a wide range of applications because they are smaller, lighter and cheaper than their traditional counterparts which are made of electrolytic capacitors. Aluminum-Polymer capacitors are typically made up of a thin aluminum foil, a ceramic dielectric material, and a ceramic polymer layer.

The working principle behind Aluminum-Polymer Capacitors is a simple one: When an electric current is applied to the capacitor, the electrons that make up the electric current are attracted to the metal aluminum foil and move towards the ceramic dielectric material. This creates a charge imbalance that eventually leads to electrostatic attraction and capacitance. When the current is removed, the opposite reaction takes place, resulting in a release of charge. This is the basic principle behind all capacitors, including aluminum-polymer capacitors.

One of the key advantages of using aluminum-polymer capacitors is their relatively low ESR or equivalent series resistance, compared to traditional electrolytic capacitors. This is due to their low thermal resistance, allowing them to store and release energy more efficiently than traditional capacitors. Additionally, due to their ceramic dielectric material, they are more reliable than electrolytic capacitors and are less likely to fail due to overvoltage or electrical surges.

Due to their low ESR and reliability, aluminum-polymer capacitors have become a popular choice for a wide variety of applications. They are used in high-power medical instruments and military applications, as well as in low-cost consumer electronics. Additionally, they are often used in automotive applications, such as power conditioning systems and electric vehicles.

The 25SEP22M aluminum-polymer capacitor is a popular choice for a wide range of applications.
