M39003/09-0362/TR

Tantalum Capacitors

The M39003/09-0362/TR is a type of tantalum capacitor. It is a polarized capacitor with a manganese dioxide cathode and a tantalum anode. It is characterized by its relatively high capacitance per unit volume, low leakage current, and stability of properties.

Application

Tantalum capacitors are mostly used in electronic applications since they are long-lasting and have excellent temperature and frequency characteristics. This makes them ideal for use in high frequency applications that require increased precision and stability, such as in radio broadcasting equipment, audio equipment, signal processing circuits, and measurement instruments. They also offer a low ESR (equivalent series resistance) which helps reduce the power dissipation in the application. Finally, they provide a high level of performance in situations where there is a high demand on stability and robustness.

Working Principle

Tantalum capacitors consist of a tantalum anode and a manganese dioxide cathode. The anode and cathode are separated by an electrolyte, usually an organic solvent, such as oxygenated organic, acetonitrile, or propylene carbonate, and a solid separator, such as paper or ceramic, to keep the cathode and anode from coming into contact with each other. When a voltage is applied, the negative charges travel to the anode, and the positive charges to the cathode. This builds up charge on either plate until the difference in potential energy reaches the breakdown field of the dielectric layer between the two plates. Once the breakdown voltage is reached, the capacitor stores a charge.

Conclusion

The M39003/09-0362/TR is an ideal choice for a tantalum capacitor, due to its high capacitance per unit volume, low leakage current, and stability. Its applications are found in a variety of high frequency and precision-driven applications due to its temperature and frequency characteristics, low ESR, and excellent performance. Finally, its working principle is based on the buildup of a charge across a tantalum anode and a manganese dioxide cathode, which is separated by an electrolyte and a solid separator. Together, this makes the M39003/09-0362/TR an ideal choice for a variety of demanding applications.
