SOLID ELECTROLYTE POLYMER TANTALUM CAPACITORS

Solid electrolyte polymer capacitors utilize sintered tantalum pellets as anodes. Tantalum pentoxide dielectric layer is formed

on the entire surface of anode, which is further impregnated with highly conductive polymer as cathode system.

The conductive polymer layer is then coated with graphite, followed by a layer of metallic silver, which provides a conductive

surface between the capacitor element and the outer termination (lead frame or other).

Molded chip polymer tantalum capacitor encases the element in plastic resins, such as epoxy materials. After assembly, the

capacitors are tested and inspected to assure long life and reliability. It offers excellent reliability and high stability for variety of

applications in electronic devices. Usage of conductive polymer cathode system provides very low equivalent series resistance

(ESR), which makes the capacitors particularly suitable for high frequency applications.
