Introduction

Tantalum capacitors are components that are extremly important for the circuit design. With the development of electronic technology, high-density and high-capacity components are required. One of the most frequently used devices meeting these requirements is TPSB475K010T1400, which is a surface mounted SMD tantalum capacitor. This article discusses the application field and working principle of TPSB475K010T1400.

Application field of TPSB475K010T1400

TPSB475K010T1400 has several application fields. It is widely used in consumer goods, such as mobile phones, digital cameras, portable medical equipments, portable data storage devices and e-book readers. It is also used in automobile electronics and industrial controlling fields. Moreover, it can be found in aerospace, military and space fields.

Working principle of TPSB475K010T1400

TPSB475K010T1400 is a tantalum capacitor. It is constructed by polycrystalline tantalum anode, MnO2 cathode, and a cathode charge material. The anode and cathode of the capacitor are made from pure polycrystalline tantalum, which is the essence of a tantalum capacitor. The anode and cathode are then plasma sprayed with cathode charge material. The dielectric materials used in the tantalum capacitor are different from those used in aluminum electrolytic capacitor.

In operation, the anode of the capacitor acts as an electrical conductor and its interconnected with the cathode. When there is a current passes through the capacitor, electrons will be attracted to the anode and leave the cathode. This creates an electric charge that can accumulates on one of the two electrodes, forming an electric field inside the capacitor. The electric field produces a reverse voltage that opposes the current, leading to the capacitor\'s energy storage.

Advantages of TPSB475K010T1400

TPSB475K010T1400 offers a wide range of advantages, including high volumetric efficiency, small size, low equivalent series resistance and high ripple current capabilities. It also offers excellent reliability, long service life and low-temperature performance. Furthermore, it is corrosion resistant and has very low leakage current.

In addition, the capacitor has a multilayer structure, which offers incomparable environmental and mechanical stability. The combination of tantalum anode and MnO2 cathode forms a layer of dielectric material between the two electrodes, enabling the capacitor to reduce the negative effects of temperature variation and high frequencies. This multilayer structure provides excellent performance and makes the capacitor suitable for high-frequency engineering designs.

Conclusion

TPSB475K010T1400 is a surface mounted SMD tantalum capacitor. It has a wide range of application fields, from consumer goods to aerospace and military fields. Its working principle is based on the combination of polycrystalline tantalum anode, MnO2 cathode and cathode charge material, which forms a multilayer structure. It offers many advantages, such as high volumetric efficiency, small size, excellent reliability and low-temperature performance. Therefore, it is a good choice and widely used in many electronic applications.
