Working Principle

The working principle of an aluminum electrolytic capacitor relies on a series of layers. It contains two metal electrodes with an electrolyte of aluminum oxide between them. The metal electrodes can be composed of aluminum or a combination of aluminum and tantalum. The electrolyte is formed by anodizing the aluminum electrode, which creates a non-conductive layer on its surface. The layer acts as a dielectric, preventing electric charges from passing through and allowing them to accumulate on the electrodes.

The negative electrode is composed of a thin layer of aluminum metal which is connected to the external circuitry. The positive electrode is composed of an oxidized sheet of aluminum, which generates an electric field when a voltage is applied across the capacitor. The electric field causes the positively charged ions to move around the oxide layer towards the negative electrode, thus causing a buildup of energy which is stored in the capacitor. Once the voltage is removed, the ions move back to their original positions and the energy is released.

The working principle of the UMF1E4R7MDD1TP range of capacitors relies on the same principle, except that the high temperature performance, low ESR, and ultra-low resistance of the capacitor make them even more reliable and efficient for a variety of applications.
