Tantalum capacitors are an important class of components in modern electronic circuits. They are widely used in various types of electronic equipment, from computer applications to consumer applications. The M39003/01-2853 is a small but powerful discrete tantalum capacitor developed by the United States military. It is a high reliability, low current leakage capacitor that is suitable for tough operating conditions. It is ideal for applications that demand a high level of reliability and robustness.

The M39003/01-2853 has a wide range of application fields, from military and aerospace to consumer electronic devices. In the military, it is used for a variety of applications, including precision guidance systems, communication receivers, special modem interface circuits, and high-power circuit switching. In aerospace applications, it is a reliable component used for various navigation and mission control functions. Consumer electronic applications include RF circuit design, audio signal amplification circuits, and other high reliability electronic circuits.

The working principle of the M39003/01-2853 can be summarised into two parts: the capacitance effect and the leakage current effect. The capacitance effect is realised through the integration of a tantalum plate with two layers of insulating metal oxide film. This forms a dielectric layer between the two conducting plates, leading to a change in the capacitance when an electric field is applied. The second part is the leakage current. It is caused by the fact that when an electric field is applied, some of the electric charge in the capacitor is ‘leaked’ out, due to the presence of imperfections in the dielectric layer between the two conducting plates.

The M39003/01-2853 is a versatile and reliable tantalum capacitor that is suitable for a variety of applications. Its high level of reliability and robustness makes it ideal for applications in the military, aerospace, and consumer electronics fields. By understanding both its application fields and working principle, engineers can be sure that they are selecting the right component for their applications.
