Introduction

Tantalum capacitors, often referred to as “tantalum electrolytic capacitors” are a type of electrolytic capacitor primarily made of tantalum metal. They are used in almost all applications where high capacitance and small size are required. These capacitors have a wide variety of applications and are used in a wide range of electronics ranging from consumer electronics to aerospace and military applications. The TH3B475M035F3100 is one such tantalum capacitor used in the electronics industry. This article will discuss the application field of the TH3B475M035F3100 and its working principle.

Application Field of TH3B475M035F3100

The TH3B475M035F3100 is a type of solid, miniaturized and low profile tantalum capacitors. They are constructed using high-purity tantalum powder with a dielectric layer of anodic oxide. These capacitors are designed for low-frequency, low-impedance applications. They are typically used in signal conditioning, filtering, smoothing AC ripple, bypassing, DC blocking and other power applications in a variety of electronic circuit designs.In the industry, the TH3B475M035F3100 offers advantages over other types of capacitors such as higher ripple current, lower internal inductance, lower equivalent series resistance (ESR) and longer service life. Its lead-free termination and small case size make it an ideal choice for automated pick-and-place assembly lines in the production of consumer and industrial electronic products. For example, they are often used in high-end smart phones, medical devices and personal computers.

Working Principle

The TH3B475M035F3100 works in accordance to the principle of dielectric polarization. This happens when an electrical field is applied between two electrodes, which causes a displacement of charge carriers. As a result, the electrical charge is stored on the electrodes, which creates a capacitance between them. This capacitance is the key feature of a capacitor which stores energy.The value of capacitance of the TH3B475M035F3100 is determined by the area of the electrodes and the distance between them. The size of the capacitor is determined by the shape and physical size of the electrodes. The TH3B475M035F3100 is designed for use in low-impedance applications, where a lower capacitance value is desired. This is achieved by using a larger electrode spacing, which reduces the capacitance value.

Conclusion

In summary, the TH3B475M035F3100 is a type of tantalum capacitor used in a wide range of applications due to its low impedance, small size and high capacitance. It is designed to handle low-frequency signals, DC blocking, AC ripple filtering and power supply bypassing. It utilizes the principle of dielectric polarization, where an electrical field is applied between two electrodes to create a capacitance. This article has provided an overview of the application field and working principle of the TH3B475M035F3100.
