Tantalum-polymer capacitors are widely used in a variety of applications due to their high capacitance, low equivalent series resistance (ESR) and low temperature coefficient of capacitance (TCC). The T55B476M010C0070 is a tantalum-polymer capacitor specifically designed for high ripple current applications. It features a 10µF capacitor value with a 4.76V working voltage and a 0.07µF equivalent series inductance (ESL).

The T55B476M010C0070 is used in applications such as filtering, power supply decoupling and low-pass filters. Its high capacitance and low ESR provide greater stability and noise suppression in these applications. In terms of physical size, the capacitor is relatively small, with a 20 x 10 x 5mm package size and a total height of 7mm. Other key specifications include an operating temperature range of -55°C to +125°C, and a maximum leakage current of 0.02mA.

The working mechanism of the T55B476M010C0070 is relatively simple. It consists of two electrodes separated by a dielectric material. The electrodes are made of a conductive material, such as tantalum metal, and the dielectric material is typically a dielectric polymer. When a voltage is applied, electrical charge accumulates on the plates due to the dielectric\'s ability to store energy. This accumulated charge creates an electric field that produces an electrical current through the capacitor\'s terminals.

When the capacitor is DC biased, the electrical charge accumulates on both the plates and the electric field remains constant. With AC bias, the capacitance is \'shunted\' across the terminals, producing an electrical current that is proportional to the frequency of the particular signal being applied. This current is then applied to the circuit, allowing the capacitor to act as a filter, suppressing noise and voltage fluctuations. The T55B476M010C0070 is specifically designed to work well under high frequency, high current AC applications.

In conclusion, the T55B476M010C0070 is a tantalum-polymer capacitor specifically designed for high-frequency, high-current applications. Its features include a 10µF capacitor value, a 4.76V working voltage and a 0.07µF equivalent series inductance. It is used in various applications such as filtering, power supplies and low-pass filters. The working principle is based on the accumulation of electrical charge on two conductive plates separated by a dielectric material, and is ideal for providing stability and noise suppression in AC biased applications.
