Tantalum Capacitors

Tantalum capacitors are among the most commonly used capacitors in electronics today. They are used in a variety of applications including military, aerospace, medical, consumer, computer, and telecommunications applications. The M39003/09-4012/HSD is a typical example of a tantalum capacitor. In this article, we will look at its application field and working principle.

Applications

Tantalum capacitors are often used for filters in AC circuits where the filter’s input needs to remain very high frequency. This type of capacitor is also used for suppression of interference in radio communications, providing a high-compactness and low cost solution for interference suppression. Examples of applications for the M39003/09-4012/HSD are automotive systems, military systems, and medical systems.In automotive systems, the M39003/09-4012/HSD can be used as a capacitive load balancing element for battery charging systems. In military systems, this type of capacitor is used in specialized power sources such as radar modules and satellites where its high voltage and low EMI (electromagnetic interference) characteristics allow it to improve the performance of critical systems. In medical systems, this type of capacitor can be used as a decoupling device, providing high frequency filtering in a high voltage environment.

Working Principle

Tantalum capacitors work on the principle of electrostatic charge transfer. This means that when a voltage is applied between two metal plates, one plate will become positively charged and the other negatively charged. The positive plate will attract electrons from the negative plate, thus transferring an electrical charge. This electrical charge can then be used to store electrical energy.The M39003/09-4012/HSD is designed to provide high current handling capabilities and low ESR (equivalent series resistance) values. The connections are titanium-plated for improved corrosion protection, and it is has an operating temperature range of -55°C to +125°C. The capacitor also has 1500 hours of lifetime rating for operation at high temperatures, and its high voltage and low inductive characteristics enable it to meet stringent electrical performance requirements. The M39003/09-4012/HSD uses a manganese dioxide dielectric, enabling it to store an electrical charge at a given voltage. Its capacitance is also very stable and predictable under varying temperatures and voltages.

Conclusion

The M39003/09-4012/HSD is a typical example of a tantalum capacitor. It is designed for a variety of applications, including automotive, military and medical systems. Its working principle is based on electrostatic charge transfer, allowing it to store energy at a given voltage. The capacitor has a wide operating temperature range and high current handling capabilities, making it ideal for a variety of applications.
