Tantalum-polymer capacitors are known in the electronics industry for their compact structure, high dielectric strength and excellent operating temperature range. Compared to other types of capacitors they offer superior energy storage and discharge performance, allowing them to operate at higher frequencies and lower voltages than ordinary capacitors. The T521V476M020ATE090 capacitor is one such component, and its application field and working principle are discussed in this article.

T521V476M020ATE090 Characteristics

T521V476M020ATE090 is a tantalum-polymer capacitor. It belongs to the 9400 series, which are typically used in applications that require a longer lifespan, higher capacitance and elevated electrical performance. They are available in a range of standard and custom sizes, with an operating temperature from -55°C to 125°C and a capacitance range of 0.1µF to 10000µF. They have a maximum working voltage of 4.8 V, and their dissipation factor is rated at 0.0015 or less. They feature high ESR and low leakage current, which makes them suitable for power supplies, military applications, and other systems that require a high degree of precision.

T521V476M020ATE090 Application Field

Tantalum-polymer capacitors are mainly used in automobiles and renewable energy systems. In the former, they are used in the feedback circuit of the alternator, to remove engine vibrations and electrical noise, and in the vehicle\'s auxiliary power systems to store energy. They are also used to increase the power of car radios, improve the performance of satellite navigation systems, and protect other components from interference. In the renewable energy sector, they are used to store energy generated from solar and wind power sources, as well as from fuel cells and batteries. They can also be used to stabilize voltage in power conversion systems.

T521V476M020ATE090 Working Principle

The T521V476M020ATE090 tantalum-polymer capacitor works by storing electrical energy and then releasing it when needed. It is composed of two electrodes (positive and negative) made of conductive material, and a dielectric material that separates them. When a voltage is applied between the two electrodes, the dielectric causes a buildup of electrical charge on the positive electrode, and a depletion of charges on the negative one. The electrical energy is thus stored, and is released when the voltage is removed. Since the energy storage capacity of the capacitor depends on its capacitance, it is important to choose the right value for the application.

Conclusion

T521V476M020ATE090 is a tantalum-polymer capacitor designed to offer superior energy storage and discharge performance. It is mainly used in automobiles and renewable energy systems, such as for stabilizing voltage in power conversion systems or for storing energy generated from solar and wind power sources. Its working principle is based on the accumulation and depletion of electrical charges on the electrodes, and the energy storage capacity depends on its capacitance.
