Tantalum Capacitors

Tantalum capacitors are an important electronic component used in a wide variety of applications. The M39003/01-7379/HSD is one such capacitor and its applications and working principles will be discussed in this article.

What is a Tantalum Capacitor?

A tantalum capacitor is an electronic component consisting of two components: tantalum and a dielectric/insulator. With the addition of the two components, it forms a basic capacitance model with which current can be stored, discharged and maintained.

Tantalum capacitors are noteworthy for their versatility, size, and reliability. In comparison to other types of capacitors, tantalum capacitors are especially small, even when containing large charges. This means that this type of capacitor can easily fit into tight, confined spaces.

M39003/01-7379/HSD Working Principle

The M39003/01-7379/HSD is a circular, polarized capacitor with two electrodes. It contains a dielectric between the electrodes with which charge can be stored and discharged. When the capacitor is charged, its core is filled with electrons, and as the capacitor discharges, electrons are released. It also requires a steady voltage source to maintain a continuous flow of electrical current through the capacitance.

The key feature of the M39003/01-7379/HSD is its high ripple current rating, meaning it can handle more power and is thus suitable for handling high-frequency signals. Its high-breaking down voltage also makes it suitable for climates of high temperature and high humidity.

Conclusion

The M39003/01-7379/HSD is a specialized series of tantalum capacitors designed for military applications. It offers a range of specifications suited for a variety of needs, including high temperature and humidity resistance, as well as high ripple current ratings. It is also remarkably small and thin, making it perfect for applications requiring space efficiency.
