M39003/03-0407/TR Working Principle

The M39003/03-0407/TR capacitor is a tantalum capacitor based on capacitance electrochemical system. It consists of an anode in the form of sintered tantalum powder, a cathode material of solid manganese dioxide (MnO2), and a solid electrolyte of niobium pentoxide (Nb2O5). When a voltage is applied, a layer of metal oxide is formed at the anode interface, which acts as a dielectric between the two electrodes. The layer of oxide is a thin film that provides a constant capacitance value for the capacitor.

The tantalum capacitor is hermetically sealed, and no external connections are required. This makes it a very reliable component – offering excellent reliability and long lifetime. Additionally, the capacitor has an extended temperature range of -55°C to +125°C, making it suitable for use under harsh environmental conditions.
