Introduction of Tantalum Capacitors

Tantalum capacitors, also called tantalum electrolytic capacitors, are electrolytic capacitors with an anode made out of tantalum metal. They are especially useful for applications that require large capacitance values in a small footprint, and in environments with stringent temperature range requirements. Tantalum capacitors have great advantages compared other types of capacitors- they can hold a large amount of energy, are small and lightweight, have low equivalent series resistance (ESR), and have excellent temperature stability.

TR3B157M004C0900 Application Field and Working Principle

The TR3B157M004C0900 is a high-performance, radial-leaded solid Tantalum capacitor with a rated voltage of 10V. It is ideal for a number of applications including DC/DC step-down converters, power supplies and voltage compensation networks. With a maximum operating temperature of +125°C and a low ESR of 0.017Ω @ 25°C, it offers a good combination of high reliability and high capacitance stability.The TR3B157M004C0900 is a radial-leaded type of tantalum capacitor. The working principle of tantalum capacitors is based on Faraday’s law of Electromagnetic Induction. The two metal layers of tantalum capacitors act as the plates of a capacitor. A dielectric material such as metal oxide separates the two layers. When a voltage is applied across the metal plates, an electric field is created and this field is responsible for inducing charges in the metal plates. This flow of charge through the dielectric material creates an electric field in the capacitor and thus creates a capacitance between the metal plates.

Advantages of Tantalum Capacitors

Tantalum capacitors offer many advantages over other types of technology. Firstly, they have high energy density, often higher than conventional multi-layer ceramic capacitors (MLCCs). This allows engineers to fit a larger capacitance into a smaller part-size category, which is particularly advantageous for space-constrained designs.In addition, their ESR is particularly low compared with other technologies, even at high frequency. This makes them well-suited for high-efficiency applications such as DC/DC step-down converters and power supplies.Finally, their temperature stability is very good, meaning that their capacitance only changes slightly over a wide temperature range, from -55¡C to +125¡C. This means that the same part can be used in a wide range of applications and environments, eliminating the need for multiple parts.

Conclusion

In conclusion, Tantalum capacitors are popular for their small size, high energy density and excellent temperature stability. The TR3B157M004C0900 is a high-performance radial-lead tantalum capacitor with a maximum operating temperature of +125°C and a low ESR of 0.017Ω @ 25°C. It is suitable for a wide range of applications including DC/DC step-down converters and power supplies, and voltage compensation networks.
