Working Principle

The M39003/01-5624/HSD Series is a type of wet tantalum capacitors. It is made of a sintered tantalum anode containing electrolytic manganese dioxide, a dielectric layer, and a conductive layer. The capacitor is also infused with an electrolyte, which helps to further enhance the capacitance and reduce the risk of leakage.

In operation, the capacitor functions according to the principles of electric double-layer capacitance and electrochemical capacitance. The electric double-layer capacitor stores energy due to the capacitance between the two electrodes, while the electro-chemical part of the capacitor is formed by the electrolyte surrounding the anode.

The electric double-layer capacitance is based on the capacitor electrodes having an affinity for charge carriers of opposite polarities. When a voltage is applied to the capacitor, the two electrodes produce a charge imbalance which produces an electric field across the dielectric layer. This electric field creates an electrostatic force which attracts charge carriers of opposite polarity to their respective electrodes, thus creating electric double-layer capacitance.

The electrochemical part of the capacitor is continually replenished by the electrolyte solution, allowing for a greater capacitance. The electrolyte solution reacts with the ions from the manganese dioxide dielectric layer, preventing dielectric failure from ion migration and surface charge reversal. This increases reliability and improves stability.

In summary, the M39003/01-5624/HSD Series of wet tantalum capacitors offers a good combination of high capacitance, good reliability, and low ESR (Equivalent Series Resistance). It is ideal for use in a wide range of applications in the telecommunications, automotive, consumer electronics, medical, and aerospace industries.
