T491A105K016AT7280 is a tantalum capacitor, a type of electrolytic capacitor. These capacitors are widespread in consumer electronics and many applications, nowadays, due to the excellent electrical characteristics of the material used in their construction. In this article, we will cover the application field and working principle of T491A105K016AT7280 tantalum capacitors.

Application Field

T491A105K016AT7280 tantalum capacitors are primarily used for filtering, decoupling and bypassing of DC power in industrial, commercial, and consumer electronics. Because of the excellent long-term reliability and stability of their electrical characteristics, they can be implemented in advanced boards and serve as filtering components. In particular, they are often used in aerospace and defense applications, as well as in medical, automotive and telecom electronics. In medical electronics, for example, they are used for voltage regulation and to filter out noise from the power lines.

In addition to filtering, decoupling and bypassing, T491A105K016AT7280 tantalum capacitors can also be employed for high-frequency signal coupling and energy storage. Various applications in industry, such as welding robotics, LED drivers, and power supplies, also often require the use of these tantalum capacitors.

Working Principle

T491A105K016AT7280 capacitors are constructed from two electrodes: a cathode and an anode, which are placed in close proximity to one another and separated by a spacer material. The spacer material is typically an insulator, such as an electrolyte, which helps to prevent short circuits between the two electrodes. The space between the electrodes is filled with the dielectric material, which allows electrical charge to flow between them when a voltage potential is applied.

In operation, the cathode is connected to the negative terminal of the power supply and the anode is connected to the positive terminal. When a voltage is applied, the capacitance between the two electrodes will increase. This increase in capacitance is due to the charge carriers in the dielectric material, which are attracted by both electrodes. As the voltage potential increases, the charge carriers become more polarised, increasing the capacitance further.

T491A105K016AT7280 capacitors are relatively small and lightweight, making them ideal for high-volume applications. Additionally, they are highly resistant to shock and vibration, making them well suited for deployment in harsh environments.

Conclusion

T491A105K016AT7280 tantalum capacitors offer many advantages in a wide range of applications. They are suitable for filtering, decoupling, bypassing, signal coupling, and energy storage applications due to their superior electrical characteristics. Additionally, their small size and weight, coupled with their resistance to shock and vibration, make them well suited for mobile and industrial applications.

In conclusion, T491A105K016AT7280 tantalum capacitors are widely used in consumer and industrial electronics, due to their excellent electrical characteristics and high reliability. With excellent performance and improved design flexibility, these capacitors are sure to be an integral part of many systems for many years to come.
