M39003/01-2455/TR

Tantalum capacitors are polarized smooth surface capacitors made of tantalum, and are available in two basic types: solid tantalum and wet tantalum. The M39003/01-2455/TR is a particular model of them. This article will discuss the application field and working principle of this tantalum capacitor.

Application field of M39003/01-2455/TR 

The M39003/01-2455/TR belongs to the small size category, making it ideal for space-limited applications such as cell phones, PDAs, laptops, or modern consumer electronics, where other capacitors are too large; they also have a relatively large capacitance for their size, enabling them to serve more demanding tasks. The tantalum capacitors have a low impedance which is very important in bypass or filtering operations.

In communication applications, M39003/01-2455/TR tantalum capacitors bring excellent stability; the tangent value of their dielectric can also accommodate high-frequency ripple. With special vertical type construction and low temperatures, they hold a good cold resistance. And their high volumetric efficiency makes them especially suitable for microelectronic applications.

Working principle of M39003/01-2455/TR 

The M39003/01-2455/TR uses the basic capacitor construction of two conductors separated by a dielectric material. In this tantalum capacitors, the two conductors are made of tantalum, and the dielectric material is generally an oxidized layer of tantalum. Although the measurement of the capacitance depends on several factors, such as the dielectric constant of the material and this same layer\'s thickness and surface area, the working principle remains the same: The electrons from the electrical charges build up surface potentials on the two conductors and produce an electric field inside the dielectric material.

When an AC voltage is applied across the capacitor, the electrons oscillate between the two conductors at the same frequency as the alternating current, forming an alternating electric field inside the dielectric material. This alternating electric field generates an energy of attraction between the two conductors, and this energy is the capacitance of the capacitor.

Conclusion

Tantalum capacitors, such as M39003/01-2455/TR, can be a versatile and powerful part of any circuit. When used for their appropriate purpose, they can be a useful and efficient capacitor to complete a desired task. Its application field and working principle has been discussed in this article.
