Tantalum capacitors are widely used passive components in electronic circuits. The M39003/01-5446/TR is a particularly reliable type of capacitor with excellent electrical and mechanical properties. It is used in both mil/aero and commercial applications for filtering, buffering, timing, and bypass applications. This article will provide an overview of the M39003 series’ application field and working principle.

Application Field of the M39003/01-5446/TR

The M39003/01-5446/TR is a polarised, axial-leaded capacitance device that combines the benefits of both ceramic and tantalum technologies. It is both rugged and reliable, and is ideal for use in high temperature, space-constrained environments, such as aerospace and defense applications. It is also useful in other commercial settings, including medical, telecommunications, and industrial electronics.

The main features of the M39003/01-5446/TR include its small size, high capacitance-to-volume ratio, and low equivalent series resistance (ESR). It is also capable of withstanding high pulse currents and can be used in high-energy storage applications as well as low-leakage timing. With its high corrosion resistance and long lifetime expectancy, the M39003/01-5446/TR is particularly popular in military, marine, and medical applications.

Working Principle of the M39003/01-5446/TR

The M39003/01-5446/TR uses a tantalum oxide-based layer as its dielectric material. When this layer is subjected to a voltage, an electric field is created which causes dielectric polarization, thus resulting in the formation of a capacitance between its two electrodes. As a result, an electrical charge is stored when current flows into one of its electrodes, and released when it flows through the other. The capacitance value of the capacitor increases with the magnitude of the voltage applied, and it therefore acts as a filter between the input and output circuits.

The capacitor also has a ESR value, which is a measure of its ability to pass and store current without a large voltage drop. The ESR depends on the thickness of the tantalum layer, and is therefore directly affected by heat, temperature, and humidity changes. The M39003/01-5446/TR is designed to handle these fluctuations without a significant reduction in its ESR, making it well suited for high-powered applications in harsh environments.

Conclusion

The M39003/01-5446/TR series of tantalum capacitors are an ideal choice for uses where reliability and performance are paramount. They’re used extensively in the aerospace and defense industries as well as in commercial and medical settings. The capacitors have exceptional electrical and mechanical properties, providing excellent performance in even the most demanding of environments. In addition, their unique structure enables them to store and release electrical charge quickly and efficiently, making them ideal for use in high-energy storage and filter applications.
