Magnetically shielded construction prevents EMI radiation. ~1.2A rated current and ~100mOhm DCR provide efficient energy storage. \/LF suffix = lead-free.","working_principle":"Ferrite core with wound copper coil enclosed in magnetic shield. Shield provides low-reluctance return path preventing field leakage. 10uH stores energy (E=0.5*L*I2) during switch-on and releases during switch-off. Ferrite saturates at ~1.5A. DCR ~100mOhm determines conduction losses.","pin_description":"
