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.","metaTitle":"Murata BLM15EG121SZ1D Ferrite Bead, 120 Ohms @ 100 MHz","metaDescription":"Murata BLM15EG121SZ1D ferrite bead, 120 Ohms @ 100 MHz, 1.5 A, 95 mOhm DCR, AEC-Q200, 0402 package.
