Tantalum - Polymer Capacitors

T540B476K006BH8610WAFL is a tantalum-polymer capacitor manufactured by Vishay. It is the smallest case-size tantalum-polymer capacitor available, suitable for use in thin mobile or other electronic designs where space is at a premium. This capacitor is designed with a Polymer Electrolyte, in order to keep high volumetric efficiency in comparison to Electrolytic Capacitors.

Application field

T540B476K006BH8610WAFL capacitors are mainly used in applications where space is a premium and for low voltage industrial and consumer applications. This type of capacitor is suitable for automotive, medical, and military applications, as well as for applications where very low leakage is required.

They are also suitable for use in audio/video circuits, pulse generators, decoupling, filtering, memory backup, and many other circuit applications, as well as in high-end power supplies, microprocessors/microcontrollers, gate drivers and more.

Working principle

Tantalum-polymer capacitors are based on a structure in which tantalum powder is deposited on a press substrate. A polymer is then applied as the dielectric, and a conductive polymer material is also used to provide electrical connection. The dielectric material used is typically an organic semiconductor, such as an amorphous silicon, or a layer created by non-volatile components, such as fullerene.

The structure of this type of capacitor is electrically symmetrical, which means that there is no polarization of the electrical field. This helps to improve the capacitance stability, and reduces ESR and DF. The capacitance range of this kind of capacitor is broad, and they are widely respected for their robust and reliable construction, making them suitable for extremely high temperature and vibration applications.
