Application Field

Due to its unique properties, tantalum-polymer capacitors are used in a variety of applications. It can be used in high-power devices such as hybrid and electric vehicles and industrial power supplies, as well as in computers, digital media player, audio amplifiers, automotive and home entertainment systems, and medical equipment. It is also often used in the military and aerospace industries for signal filters and RF power circuits. Additionally, due its long-life span, this technology lends itself to applications that require high reliability and robustness, such as mission critical systems, aerospace and defense products, and automotive body control systems.

Working Principle

Tantalum-polymer capacitors are manufactured from a matrix of alternating layers of polymer and tantalum. It is this unique combination of materials that gives the capacitor its superior performance and superior temperature stability over traditional tantalum capacitors. The layers of polymer provide flexibility and lower ESR, while the tantalum provides increased capacitance and temperature stability. The combination of these two materials also gives the capacitor increased load life and an extremely low failure rate. It also increases the amount of energy that can be stored for use.

Tantalum-polymer capacitors are typically charged with an electric current, creating a layer of ions. The ions are then held across the alternating layers of polymer and tantalum, forming a charge. When a voltage is applied, the capacitor stores the electrical energy, which can then be used for various applications. It can also store electrical energy as charge, allowing it to maintain its voltage for a much longer period of time.

Tantalum-polymer capacitors are well-suited to many different applications because of their reliability and durability. They are resistant to corrosion and can withstand extreme temperatures, making them ideal for use in high-temperature applications. They are also highly efficient, providing up to 95% efficiency, which means they require less energy to charge and discharge than other capacitor technologies. Additionally, they are very lightweight and compact, adding to their versatility.
