Working Principle

The M39003/03-2065 is a solid-tantalum capacitor, which consists of a tantalum anode core and a solid electrolyte. The anode consists of a sintered powder, which acts as a cathode for the electrons. The anode is surrounded by a dielectric layer which prevents arcing and leakage. The solid electrolyte layer, which can be either a plastic or a polymer, acts as an ionic conductor. During operation, a potential difference is applied across the anode and the cathode, which generates a current and charged ions move from the anode to the cathode.

The closing of the ions forms a capacitive element, which store electrostatic energy. As the ions move away from the capacitor, the stored energy is released and the capacitor discharges. The capacitance of the capacitor is determined by the size and configuration of the anode and cathode, as well as the nature of the dielectric and electrolyte. Depending on the configuration, the required capacitance can be tuned to the desired value.
