The BLM15EG121SH1D is a single-line ferrite bead from Murata's BLM15EG series, in the 0402 (1005 metric) package. It provides 120 Ohms of impedance at 100 MHz, which is the frequency where most conducted EMI from switching converters and digital logic sits — so this bead knocks down that noise before it reaches the power rail or signal line.
