EQUIVALENT CIRCUIT MODEL FOR TANTALUM AND …

The dielectric of a real capacitor is not an ideal insulator, so there is a leakage current through the component. Furthermore, Tantalum and Niobium Oxide capacitors are polar components, and due to the MIS structure [1] of the capacitor, the leakage behavior under reverse voltage is similar to a diode''s VA characteristic - with a sharp knee at
