The BLM15EG121SZ1D is a single-line ferrite bead from Murata's BLM15EG series, rated 120 Ohms impedance at 100 MHz and 1.5 A continuous current. The 120 Ohm peak at 100 MHz targets conducted EMI in the 30–300 MHz range — common for switching noise from DC-DC converters and digital logic. Above 1.5 A the ferrite material begins to saturate, dropping the effective impedance; stay below this ceiling to maintain the specified attenuation.
120 Ohms at 100 MHz, rated for 1.5 A continuous current with a maximum DC resistance of 95 mOhm.
