Aluminum - Polymer Capacitors

Aluminum–polymer capacitors are a type of reliable, non-solid electrolytic capacitor, made of a dielectric formed of a semiconducting material, typically aluminum oxide, and a conductive electrode layer of either aluminum or tantalum. They are also known as aluminum electrolytic capacitors due to the fact that they use an aluminum oxide dielectric material to increase the capacitance. Their unique design and construction allows them to have superior capacitance, voltage, temperature, and stability performance compared to ceramic or tantalum electrolytic capacitors.

870235674003 Application Field

Aluminum-polymer capacitors are used in a variety of electronic products, from air conditioners and refrigerators to lighting and telecommunications equipment. They are also used in the automotive industry for their stability and reliability, and can be used in computer systems and touch screens due to their low ESR. In addition, these capacitors are used in the power supply and battery charger circuits of small electronics such as: cell phones, portable computers, notebook computers, and digital cameras.

870235674003 Working Principle

The working principle of an aluminum-polymer capacitor is based on the charge storage mechanism of an electric field where a layer of aluminum oxide is placed between two aluminum layers. The electric field created by the stored charge redistributes the charges in the capacitor resulting in a higher capacitance. The capacitance increases due to the improved ability of ions to move from one layer to another. The aluminum oxide layer prevents charge leakage and provides a dielectric between the aluminum layers. This helps to increase the stability and reliability of the aluminum–polymer capacitor.Due to the aluminum oxide layer, the aluminum–polymer capacitor also has higher temperature stability and can handle larger voltages than traditional electrolytic capacitors. The layer of aluminum oxide also ensures that no dielectric absorption occurs, which can lead to capacitor failure. In addition, aluminum-polymer capacitors have low ESR values, which makes them suitable for use in power supply and battery charger circuits. The low ESR also makes these capacitors particularly suitable for high-frequency applications such as power supplies and motor drives. Aluminum-polymer capacitors also have a long service life, making them more reliable and cost- effective than other types of capacitors. The capacitors also have low leakage current and low noise levels. Overall, aluminum-polymer capacitors are designed to provide superior performance, reliability and cost-effectiveness. They are ideal for a variety of applications, particularly in power supply and battery charger circuits. Their high capacitance and temperature stability, as well as their low ESR, make them the perfect choice for use in high-frequency applications.
