Tantalum capacitors usually use tantalum as an anode. There is a layer of oxide film on the tantalum anode. The oxide film acts as a dielectric. The cathode is usually made of manganese dioxide. The tantalum capacitor has the characteristics of high electrical capacity and small volume. Some tantalum capacitors have extremely high volumetric efficiency approaching 1000μF/cc and are currently the highest existing capacitance of solid capacitors.

The working principle of M39003/01-2275/HSD is based on the conventional capacitor principle. When a potential difference is applied between the two electrodes of the tantalum capacitor, the opposite charges move to the surface of the electrodes. A depletion layer is formed on the surface of the electrodes, and the two surfaces of the electrodes are separated from each other, forming an insulator. The width of the insulator between the two electrodes is proportional to the applied voltage of the tantalum capacitor, and the capacitance value is proportional to the area of the insulator. The charge stored by the tantalum capacitor is related to the voltage applied to the capacitor and its capacitance. When a voltage is applied to a tantalum capacitor, a current will flow through it during the charging period. As the voltage on the capacitor increases, the current decreases.

In summary, M39003/01-2275/HSD is a kind of tantalum capacitor with advanced features, which can be widely used in the automotive, avionics and medical industries. Its working principle is based on the conventional capacitor principle, which is related to applied voltage and capacitance of the capacitor.
