Tantalum Capacitors

Tantalum capacitors are widely used in the modern-day electronics industry for their unique properties and exceptional stability. Featuring a high capacitance-to-volume ratio, low leakage, and excellent electrical characteristics, Tantalum capacitors are at the cutting edge of the industry in terms of performance. One such capacitor, the M39003/01-7012/TR, is used in a variety of applications in the electronics arena, and its working principle can be explained with the help of a few diagrams.

Application Field

The M39003/01-7012/TR capacitor is typically used in consumer electronics, such as cell phones, laptops, and game consoles. It is also commonly used in industrial and automotive applications, due to its ability to withstand wide voltage ranges and high temperatures. It is also highly suitable for high current applications, and commercial power supplies, which require a large amount of capacitance in a small package.

Working Principle

The working principle of the M39003/01-7012/TR capacitor has to do with its internal construction, which consists of a casing made of tantalum metal and an electrolyte, such as manganese dioxide. When a voltage is applied across the capacitor, the electrons from the positive terminal move towards the negative terminal. When they reach the negative terminal, they react with the electrolyte and form an electric double layer, which stores electric charge. This electric double layer then acts as a barrier which prevents further flow of electrons, resulting in a stored charge that remains constant until the voltage is removed.

The capacitance of the M39003/01-7012/TR depends on the relative permittivity of the internal dielectric material (e.g., manganese dioxide) and the plate area of the capacitor. As the plate area is increased, and the permittivity remains the same, the capacitance increases as well. As such, the M39003/01-7012/TR is ideal for high current applications, as the amount of current stored is proportional to the surface area of the capacitor plates.

Conclusion

For its ability to withstand wide voltage ranges and high temperatures, as well as its high capacitance-to-volume ratio and low leakage current, the M39003/01-7012/TR capacitor is an excellent choice for use in consumer electronics, power supplies, and high current applications. The capacitor\'s working principle, which relies on the formation of an electric double layer to store charge, is simple yet effective.
