Working Principle

LLS1K272MELA aluminum electrolytic capacitor consists of two metal plates with an oxide film layer as the dielectric between them. During the manufacturing process, a solid oxide electrolyte is applied on the metal plate and attracts ions of the electrolyte material into the dielectric layer. The anode is aluminum foil. When a voltage is applied across the capacitor, positive ions travel through the dielectric to the negative foil plate and a current is developed within the capacitor. The current collected by the metal plate on the anode forms a conductive layer on the dielectric oxide film, which is called the Faradaic current layer.

As the applied voltage increases, more positive ions move through the dielectric, forming an asymmetric layer until a full charge is achieved. At this point, when the external voltage exceeds the charge voltage, the electric field across the capacitor will become stronger, causing the Faradaic current layer on the dielectric to expand and reduce the capacitance of the capacitor. This is the working principle of LLS1K272MELA aluminum electrolytic capacitors.
