Aluminum-Polymer Capacitors

Aluminum-Polymer Capacitors are electronic components that consist of two aluminum electrodes separated by a dielectric polymer material. They are used in a wide range of applications that require a high-capacity capacitor with low leakage and minimal ESR. They are widely used in RF circuits, medical and lighting applications, automotive, telecom, military and broadcast equipment and even in consumer electronics.

870235673001 Application Field And Working Principle

Aluminum - Polymer Capacitors are widely used in high frequency, high current applications such as radio frequency (RF) communication. The capacitance of the aluminum-polymer capacitors ranges from 0.005 to 1000µF. They are applicable for a wide range of voltages from 63VDC to 850VAC.

The dielectric material employed in Aluminum-Polymer Capacitors is of polymeric. Generally, the polymeric materials contain an inorganic filler or ceramic, between the aluminum and the polymer that provides stability to the dielectric material. The dielectric polymer material is the responsible element to achieve high capacitance values. The polymer is characterized by its excellent electrical and thermal properties, it\'s able to maintain stable electrical performance over a wide range of temperatures.

The working principle of an aluminum-polymer capacitor is the same as any other capacitor: it is a device that stores energy when a voltage is applied to it. When a voltage is applied to an electrolytic capacitor, electrons move from one of the electrodes to the other, creating a positive charge on the positive electrode and a negative charge on the negative electrode. This can be likened to a battery, with the positive electrode being the anode and the negative electrode being the cathode.

In addition to high capacitance, the aluminum-polymer capacitors have exceptional capacitance stability and low ESR compared to other capacitors. They also have a robust dielectric that can withstand high voltages as high as 850VAC or 1000VDC. Furthermore, they are highly reliable and long-lasting with up to 5 million cycles.

Aluminum-polymer capacitors are ideal for high-frequency, high-current electronics and a variety of other applications. They provide superior performance and reliability compared to other types of capacitors, such as tantalum, aluminum electrolytic, and ceramic capacitors. Additionally, they are low-leakage capacitors designed to handle extreme temperatures and conditions.
