Tantalum Capacitors

A good example of a tantalum capacitor would be the M39003/03-3080/98. This type of capacitor is a solid electrolytic capacitor with an anodized tantalum cathode body and an organic/polymer cathode dielectric. The solid electrotypic capacitors have a higher value of capacitance than other types of capacitors, making them well suited for high-efficiency applications. The organic/polymer cathode dielectric layer is also ideal for applications requiring tight tolerance components.

Application Field

The M39003/03-3080/98 is specifically designed to meet the demanding requirements of electronic systems in a variety of applications such as defence, aerospace, automotive, communication, medical, computing, telecommunication, and industrial electronics. Specifically, the capacitor is used for smoothing, filtering, and decoupling in power supply circuits, as well as in analog and digital communication circuits. In addition, the capacitor is also used in RF no-spill current devices, voltage regulators, voltage-controlled power supplies, and in various sensor and transducer designs.

Working Principle

Tantalum capacitors are based on the principle of capacitive charge displacement. This means that when a voltage is applied across the two terminals of a capacitor, the capacitor will start to absorb the charge that is being applied from the external source. This process is known as capacitance. As the voltage continues to increase, the capacitor begins to store the electrical energy, this is because the electrons that make up the voltage are stored in the capacitors anode and cathode dielectric layers. As the voltage level continues to increase, the electrons begin to flow from the anode to the cathode of the capacitor.

The capacitance of the M39003/03-3080/98 is very high, with a rated capacitance of 3.2uF and a rated voltage of 6.3V. This makes it an ideal choice for applications that require high-efficiency components. In addition, the organic/polymer cathode dielectric layer provides excellent tolerance and stability.

Conclusion

The M39003/03-3080/98 is a reliable and versatile capacitor that is well suited for a variety of applications in the defence, aerospace, automotive, communication, medical, computing, telecommunication, and industrial electronic fields. Specifically, the capacitor is used for smoothing, filtering, and decoupling in power supply circuits, as well as in analog and digital communication circuits. Furthermore, the capacitor is very durable and has a high level of performance. The high capacitance and low ESR also make it ideal for high-efficiency applications.
