AEC-Q200 qualified for automotive applications, it provides approximately 2.8A rated current and 3.5A saturation current with ~25m\u03a9 typical DCR. The magnetically shielded construction contains flux within the component, reducing EMI coupling. Operating from -40\u00b0C to +125\u00b0C, it is designed for automotive DC-DC converter and power filter applications.","working_principle":"The SRU5028A uses a ferrite composite core with wirewound construction enclosed by a magnetic shield. The shield contains the magnetic flux within the component volume, preventing radiated EMI from coupling to adjacent circuit traces. The ferrite composite core provides high saturation flux density for high current handling in a compact footprint. The low DCR (~25m\u03a9) minimizes copper losses for high converter efficiency.","pin_description":"
