Working Principle

The LAL03VB391K is composed of an inductor loop and a capacitor connected in series. The inductor loop consists of a ferrite core and a coil of wire wound around the core. Electric current flows through this coil when a voltage is applied across the two terminals. As the electric current flows through the coil, a magnetic field is generated, which generates a force that opposes the change in current flow. At the same time, the capacitor absorbs the voltage fluctuations. In other words, the combination of inductor and capacitor in the LAL03VB391K maintains constant voltage across the device and regulates the current flows.
