SMM02040D1202BB300 is a high-current, magnetically shielded, surface-mount (SMD) power inductor. Its core function is to serve as an energy storage and filtering component in circuits such as switch-mode power supplies (DC-DC converters). It smoothens current, suppresses high-frequency noise, and can withstand significant DC current without saturating.
