Tantalum capacitors are used to store energy in electronic circuits. They are becoming increasingly important as the demand for higher functionality, greater reliability, and improved packaging technology from electronic devices increases. The M39003/01-5071 is a very versatile tantalum capacitor for use in all kinds of electronic applications. This article provides an overview of the M39003 application field and the working principle of its tantalum capacitor.

M39003 Capacitor Application Field

M39003 capacitors are widely used in a variety of military and aerospace applications. They are frequently found in military aircraft, missiles, ground vehicles, shipboard systems, and satellite systems. This capacitor is reliable and rugged enough to endure the extreme temperatures and vibration of such operation. It is hermetically sealed for protection against harsh physical and environmental elements, with a low impedance to minimize interference. The M39003 is also qualified to MIL-PRF-55347G, which makes it suitable for a wide range of applications.

Working Principle of Tantalum Capacitors

Tantalum capacitors are non-polarized electrolytic capacitors, which means that they use two electrodes of opposite charge (an anode and a cathode) that are separated by an electrolytic solution (often tantalum pentoxide). The capacitance of the capacitor is determined by the amount of charge stored on the electrodes. This charge is controlled by the thickness of the electrode and the thickness of the electrolyte solution.

When a voltage is applied across the anode and cathode, ions from the electrolyte solution will either be attracted or repelled depending on their charge, which creates a potential difference between the two electrodes. This electric field produces an electric current, which is the basis for a tantalum capacitor\'s operation. The electric field is maintained as long as the voltage across the capacitor is greater than the breakdown voltage of the electrolyte.

Tantalum capacitors can be used in a variety of applications, such as power management, filtering, signal coupling, and bypassing. They offer several advantages over other types of capacitors, such as high capacitance, low ESR, small size, light weight, and low self-inductance. They are also highly resistant to temperature and voltage fluctuations, making them ideal for use in harsh environments.
