Tantalum capacitors are unique components that are essential for the implementation of modern electronics, commonly used in analog, digital, and in a variety of power supply circuits. The M39003/01-2620/98 is a commonly used, military-grade, axial leaded type of tantalum capacitor with a wide range of uses and applications. This article will discuss the application field and working principle of the M39003/01-2620/98 in detail.

Construction and Sizes of the M39003/01-2620/98

The M39003/01-2620/98 is a type of metalized, Ta anode capacitor and its construction basically consists of two parts: the anode, which is a Ta-oxide barrier layer; and the cathode, made of a Ta-oxide film. The anode side is further covered with a metalizion layer of a metal oxide. An additional layer of Ni-plated MnO2 is also included for electrode protection. The maximum rated voltage of this capacitor is 16V and the maximum capacitance rating is 560μF, however, it is available in different sizes ranging from 5mm x 11mm all the way up to 38mm x 44mm.

Application Fields and Working Principle of the M39003/01-2620/98

The M39003/01-2620/98 is mainly used in an array of military and commercial applications due to its superior characteristics such as low leakage current, low ESR, high ripple currents and temperature stability. This type of capacitor is mainly used for signal filtering, small signal coupling and noise reduction, power bypassing in low noise circuits, power source decoupling, and oscillator blocking.

The working principle of the M39003/01-2620/98 relies on the fact that when a voltage is applied across its terminals, a capacitance value is created due to the polarization of its layers. This anode layer is electrically charged to a certain voltage and the negative electrode layer creates a capacitance between the two layers. The capacitance will gradually increase with increasing voltage, up to the maximum specified voltage.

The main advantage of the M39003/01-2620/98 is that it offers a relatively low frequency performance, with a deep depth of discharge and low ESR. It is also temperature compensated and extremely resistant to voltage spikes and power surges. Its containment can withstand high temperatures and is very suitable for power and industrial application fields, as it offers reliable operation and long-term stability.

Conclusion

In summary, the M39003/01-2620/98 is a type of military-grade metalized tantalum capacitor, available in different sizes and with a wide range of applications. Its advantages include low leakage current, low ESR, high ripple currents and temperature stability, making it suitable for a variety of military and commercial applications. This tantalum capacitor offers reliable operation and long-term stability, making it an excellent choice for signal filtering, circuit coupling and noise reduction.
