Tantalum capacitors are electrical capacitors with tantalum oxide as a dielectric medium, usually formed into a solid, cylindrical structure, with an electrolytic solution between layers of anode and cathode metal. They are used in many electronic circuits to store and release electrical energy and are in various applications across a variety of industries. M39003/03-4002 (M39003/03-4002) is one dedicated type of tantalum capacitor.

The main application for M39003/03-4002 is in space missions due to its small size and low weight, which makes it well suited for mounting on spacecrafts with limited size and weight restrictions. The device is also used in military equipment and other safety-critical applications, such as avionics, automotive electronics, energy storage, and mission-critical computer systems. It can also be found in power supplies, field-programmable gate arrays, audio amplifiers, and other energy-saving components.

The device’s working principle is based on the fact that it stores energy through the formation of an electric double layer between the dielectric oxide and the surface of each electrode. The electric field across the built-in capacitance causes electrons to accumulate on the interface of the oxide and electrode, leading to a reversible polarization which acts as a dielectric. The result is an electric field between the electrodes, allowing electrons to pass freely between them and storing energy.

In operation, the capacitance of the M39003/03-4002 capacitor is changed by applying a voltage to the terminals, increasing the capacitance exponentially with greater voltage. The device can also tolerate high temperatures and harsh environments; its unique construction allows for minor impurities and long terms stability. Due to their small size and light weight, M39003/03-4002 tantalum capacitors are thus widely used in space missions, military equipment, and other safety-critical applications.
