Tantalum - Polymer Capacitors

Tantalum-polymer capacitors are gaining increasing popularity in various electronics applications. This capacitor type combines the features of tantalum electrolytic and polymer film technology, offering high capacitance, ultra-low ESR, and long-term reliability. This combination of features makes it possible to reduce board space and optimize power delivery in a wide range of application scenarios.

4TPF680MAH application field

The 4TPF680MAH is a type of tantalum-polymer capacitors designed for improving the power delivery performance of power management modules of computing systems. It also has applications in telecommunications equipment, cameras and surveillance devices, light sources, and in automotive and medical equipment. The 4TPF680MAH offers excellent power delivery performance, high reliability, and very small size for efficient board space optimization. The device can operate over wide range of temperatures, making it suitable for power-delivery application in harsh environments.

Working principle

Tantalum-polymer capacitors utilize the advantages of both tantalum and polymer construction. This capacitor features a solid polymer electrolyte, rather than traditional liquid electrolyte, that is particularly useful for its high-temperature working capability and reliability. They also feature highest capacitance-to-volume ratio among other types of capacitors and achieve ultra-low ESR, which makes 4TPF680MAH more space efficient for power delivery.

The unique construction of 4TPF680MAH defines its working principle as well. This device is constructed from solid tantalum electroplated with a layer of tantalum hydroxide and connected with a solid polymer electrolyte. This positive electrode is further connected to the negative electrode, which is made from stainless steel. The ac signals get delivered through an anode and cathode connected to the solid polymer electrolyte. When the current flow changes, the capacitor gets charged and discharged accordingly.

When the capacitor is used in an application, the charge is balanced between the anode and cathode. The voltage is then transferred by the polymer electrolyte and the capacitor is ready to store energy. This process is repeated as the application requires and makes 4TPF680MAH a reliable energy storage device.

Due to its superior performance and reliability, 4TPF680MAH has found applications in a wide range of industrial, commercial, and consumer applications. Its ability to deliver reliable power in harsh environments and its small size have made it an ideal power delivery solution for many electronics applications.
