75 Ohm @ 100 MHz, 0402 signal-line ferrite bead
The Murata BLM15BX750SN1D is a single-line ferrite bead from the EMIFIL® BLM15 series, offering 75 Ohms impedance at 100 MHz in a standard 0402 (1005 Metric) surface-mount package. Rated for 600 mA continuous current with a maximum DC resistance of 150 mOhm, this bead is sized for low-voltage signal rails where the DCR voltage drop must stay under 90 mV at full load.
The BLM15BX base number is the same family, so date-code continuity is stable for BOM planning.
