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.
120 Ohms at 100 MHz, which is the standard reference frequency for ferrite bead EMI suppression. This impedance is effective for filtering conducted noise from switching regulators and high-speed digital lines in the 10 MHz to 300 MHz band.
Yes, it carries an AEC-Q200 rating, meaning it has passed automotive-grade passive component reliability testing including thermal shock, moisture resistance, and vibration.
