Tantalum capacitors, also referred to as tantalum electrolytic capacitors, are small, non-polarized, electrolytic surface mount capacitors with a high capacitance-to-volume ratio. They are characterized by their low ESR (equivalent series resistance) and low DC leakage. The T86E476M020EBSS is a multilayer, high-temperature, automotive-grade, surface mount tantalum capacitor. It features a broad capacitance range between 4.7F and 22F, and a voltage rating of up to 20V.

Tantalum capacitors are suitable for automotive, industrial, and consumer electronic applications. In the automotive sector, these components can be used for power filtering in engine control systems, HVAC, and audio amplifiers. In industrial applications, they are used in flow-control systems, telecommunications systems, and industrial robots. In consumer electronics, they are commonly used in cell phones, portable media players, and audio systems.

The working principle of a tantalum capacitor is based on the Helmholtz double layer principle. This type of capacitor is constructed of two electrodes that are immersed in a conductive electrolyte material. When a voltage is applied to one of the electrodes, a positively charged layer, known as a Helmholtz double layer, forms at the interface between the electrodes and electrolyte. This thin layer is electrically active and is responsible for the capacitive action.

The T86E476M020EBSS is a surface mount device that is composed of an anode body, a cathode contact, a tantalum cathode element, a metal folio separator, and a dielectric. It also has a drain wire that connects the anode body to the folio separator. The component is designed to provide superior temperature resistance (max operating temp. of 125°C) and excellent power derating characteristics. This makes it especially suitable for automotive systems and other high-temperature applications.

The T86E476M020EBSS features a robust construction and is designed for use in soldering reflow operations. The component is composed of a metal-semiconductor junction, which prevents short-circuiting during the reflow operation, and allows safe soldering of the component. Thanks to its design and composition, the component features high capacitance values, excellent temperature stability, and superior esr performance.

The T86E476M020EBSS has a wide range of applications in automotive, industrial, and consumer electronic applications. It is used for power filtering, HVAC systems, audio amplifiers, telecommunications systems, and industrial robots. In consumer electronics, it is used in cell phones, portable media players, and audio systems. Thanks to its great features, it is an ideal choice for any application requiring a small, high performance capacitor.
