The shielded construction uses a ferrite core with a magnetic shield that contains the magnetic flux within the inductor body, preventing EMI radiation to nearby components. The 3226 footprint (3.2 x 2.6mm) offers a good balance between current handling capability and board space. The wire-wound construction on a ferrite drum core provides low DC resistance for high efficiency and high saturation current for reliable operation under heavy load transients.","working_principle":"The LSR32643 power inductor stores energy in its magnetic field when current flows through the winding. In a buck converter, the inductor smooths the pulsed output of the switching transistor, converting the rectangular PWM waveform into a DC output with minimal ripple. During the switch-on period, current increases linearly (V = L \u00d7 di\/dt) and energy is stored in the ferrite core's magnetic field. During the switch-off period, the inductor maintains current flow through the freewheeling diode, releasing stored energy to the load. The magnetic shield provides a low-reluctance return path for flux, preventing coupling to adjacent traces and components.","pin_description":"
