Tantalum capacitors offer a range of advantages when compared to other types of passive components, making them a popular choice among electronic and electrical engineers. The M39003/01-8331/TR tantalum capacitor is a member of the family of tantalum capacitors used in high reliability applications. This article provides an overview of the application field and working principle of the M39003/01-8331/TR tantalum capacitor.

Tantalum Capacitor Overview

A tantalum capacitor is a type of electrolytic capacitor, with the most common type being the solid electrolytic capacitor. In these types of capacitors, the anode is composed of a tantalum powder and the cathode is a paper-based material such as manganese dioxide. The capacitor’s dielectric, or insulating material, is a thin oxide layer formed when the anode is oxygenated in an electrolyte solution. Due to their construction, tantalum capacitors offer a number of benefits and are frequently used in high reliability applications.

M39003/01-8331/TR Capacitors

The M39003/01-8331/TR tantalum capacitor is a type of molded tantalum capacitor used in military and aerospace applications. It offers a range of advantages over other types of capacitors, including increased reliability, higher capacitance per volume, lower series inductance, and higher temperature operation, thanks to its superior temperature coefficient of capacitance. The M39003/01-8331/TR is configured in a hermetically-sealed metal can, featuring a nickel-plated aluminum shell with a stainless steel nipple and a baked-on epoxy sealant. This design helps to ensure the capacitor’s reliability and performance in extreme environments.

Application Field and Working Principle

The M39003/01-8331/TR capacitor is designed for use in harsh operating environments such as high temperatures, moist atmosphere, severe vibration, electrical surge, and shock. It is particularly well-suited for military and aerospace applications including power, aviation, instrumentation, and munitions systems. In these applications, its high capacitance per volume, low series inductance, and excellent temperature coefficient of capacitance make it an ideal choice.

As with other tantalum capacitors, the M39003/01-8331/TR capacitor works on the principle of charging and discharging. When the capacitor is connected to a voltage source, the anode will begin to accumulate electrons and charge up. When the voltage source is disconnected, the extra electrons stored in the anode will discharge, storing electrical energy until the power source is reconnected, resulting in an electric current.

Conclusion

The M39003/01-8331/TR tantalum capacitor is an ideal choice for a range of military and aerospace applications, offering superior performance and reliability compared to other types of capacitors. Its hermetically-sealed metal can ensures its protection in harsh operating environments, and its ability to store electrical energy efficiently makes it an indispensable component for power, aviation, instrumentation, and munitions systems.
