Working Principle

At the core of the M39003/09-0317 is a layered structure consisting of a solid, curved anode, a cylindrical separator, and a solid, flat cathode. The anode is formed by sintering tantalum powder, while the cathode is composed of manganese dioxide. The two electrodes are separated by a dielectric separator and immersed in an electrolytic solution.

When voltage is applied to the capacitor, electrical current flows through the electrolytic solution and onto the anode. This reaction results in the formation of an oxide layer on the anode, which acts as an insulator and increases the capacitance of the capacitor. As current flows through the capacitor, a small amount of heat is generated, which is dissipated by the anode’s solid heat conductive structure.

The M39003/09-0317 also features a reliable seal system, which provides protection against the intrusion of liquids and contaminants into the inner workings of the capacitor. The capacitor is also equipped with an improved design, which enhances its performance in environments with higher temperatures and humidity.
