Tantalum capacitors are one of the most common components found in modern electronic circuits and are employed in a variety of different applications. The M39003/03-3017 is one such capacitor, specifically designed for military and space applications. It is important to understand the device’s working principle and application field in order to properly employ it.

The M39003/03-3017 is a high-reliability, axial leaded, insulated tantalum capacitor with voltage ratings of 12V and 25V, and capacitance values ranging from 0.22µF to 33µF. These capacitors come equipped with a titanium-plated case, epoxy resin seal, and a special green semiconductor Silicon Rubber coating. Together, these components make the M39003/03-3017 suitable for operations in extreme temperature and shock/vibration environments.

The M39003/03-3017 operates according to the same basic principle as all other tantalum electrolytic capacitors. It relies on a layer of tantalum pentoxide, which acts as a dielectric, sandwiched between two metal plates. The first plate, which is the anode of the capacitor, is composed of tantalum while the second, which is the cathode, is made from a manganese dioxide pellet. A solution of sulfuric acid is used to keep the plates in contact with each other and to act as the electrolyte of the capacitor. As a voltage is applied to the plates, a current of ions flows from the sulfuric acid to the tantalum and manganese dioxide layers, forming a capacitor.

The high reliability of the M39003/03-3017 makes it well suited for use in mission critical systems, such as aviation and military electronics, as well as in harsh industrial environments. Its ability to withstand extreme temperatures and shock/vibration, combined with its high capacitance values, makes it an ideal choice for applications such as filtering, energy storage, and pulsed power. In addition, it is also commonly used in telecommunications and radio frequency (RF) applications.

The M39003/03-3017 tantalum capacitor shows excellent performance in challenging environments, making it a popular choice for many different kinds of electronic applications. It is characterized by a high capacitance value and reliable operation, making it suitable for use in mission critical systems. Its ability to operate at extreme temperatures, shock, and vibration allows it to be used in harsh industrial and military/aviation environments.
