With 1A rated current, 450mA saturation current, and 75m\u03a9 maximum DCR, it provides efficient energy storage and transfer in DC-DC converter applications. The magnetically shielded construction minimizes EMI coupling to nearby components. AEC-Q200 qualified for automotive use, it operates from -40\u00b0C to +125\u00b0C in a compact 6.6x4.45x2.92mm surface-mount package.","working_principle":"The WE-PD3 uses a ferrite core with wirewound construction enclosed by a magnetic shield. The shield contains the magnetic flux within the component, preventing coupling with adjacent traces or components that could cause EMI issues. The ferrite core provides high permeability for the specified inductance. Saturation current (450mA) is defined where inductance drops 10% from nominal. The rated current (1A) is defined by 40\u00b0C temperature rise from DCR losses.","pin_description":"
