Tantalum capacitors are electronic components used to store electrical and thermal energy, as well as for bypassing and decoupling functions. In particular, they are often used where a large, semi-permanent charge is necessary. The M39003/03-3051 is a type of tantalum capacitor that is particularly used in military-grade and space-grade applications.

This capacitor needs to meet requirements for extreme environments, including temperature, vibration, temperature shock, radiation, humidity, and fogging. To meet these requirements, the capacitor is constructed with an anodized metal shell, and features a tightly sealed design so as to prevent moisture from entering and corroding the capacitance material. The shell also provides for excellent mechanical strength.

The capacitor features a compact design that is well-suited for use in smaller printed circuit boards, while the high voltage ratings – up to 450V – make it well-suited for power supply designs. These ratings are indicative of its high reliability, as well as its suitability for long operational life.

The working principle behind the M39003/03-3051 lies in the Faraday effect. This effect describes how a voltage applied to a dielectric material changes the polarization of the material, and the capacitance. The polarization of the material is proportional to the voltage applied, and the dielectric material provides a link between the electrodes of the capacitor. When a voltage is applied to the capacitor, the dielectric material polarizes, creating a potential between the electrodes. This potential is directly proportional to the charge stored in the capacitor. The higher the potential, the more charge is stored, and the greater the capacitance of the capacitor.

Due to its excellent reliability and suitability for a variety of applications, the M39003/03-3051 tantalum capacitor is an ideal choice for military-grade and space-grade applications. Additionally, its non-polarized design and high voltage ratings make it an ideal choice for industrial power supplies, automotive applications, telecommunication systems, and more.
