It is designed for high-efficiency DC-DC converter applications requiring low EMI and high saturation current.","working_principle":"The inductor stores energy in its magnetic field when current flows through the winding. In a buck converter, the inductor smooths the pulsed switch output into a continuous DC current. The shielded construction contains the magnetic flux within the core, minimizing EMI coupling to nearby circuits.","pin_description":"
