Working Principle

The working principle behind T520D227M010ATE025 tantalum-polymer capacitors is based on a dielectric layer of tantalum pentoxide deposited on a substrate with a conductive-polymer anode. The anode acts as a charge collector and increases the capacitance. When a voltage is applied, the positive ions in the tantalum pentoxide layer migrate to the anode and an electric field is established. This electric field creates an opposing electrical field between the electrodes which is what gives the capacitor its capacity to store energy.

The capacitor\'s capacity is determined by the size of the electrode surface, the type of conductive-polymer used and the thickness of the dielectric layer. The material of the electrodes affects the amount of current that can pass through the capacitor, as well as its voltage rating and capacitance values.
