600 Ohms @ 100 MHz — the suppression spec that defines the fit
The BLM15BD601SH1D is a single-line ferrite bead from Murata's EMIFIL®, BLM15 series, delivering 600 Ohms impedance at 100 MHz. This is the figure that determines how much high-frequency noise is attenuated on the line — the 600 Ohm target at 100 MHz is typical for suppressing switching noise from DC-DC converters or clock harmonics in the 50–200 MHz band. Rated for 200 mA continuous current, with a maximum DC resistance of 650 mOhm. The DC voltage drop across the bead at full rated current is 130 mV — budget this into the rail voltage if the bead sits on a power line rather than a signal line.
AEC-Q200 and 125°C — automotive-grade thermal margin
Qualified to AEC-Q200, the automotive passive-component stress test standard.
Supplied in Tape & Reel (TR) or Cut Tape (CT) packaging for pick-and-place assembly. The base product number BLM15BD covers the family; the full suffix SH1D specifies the impedance grade and packaging variant.
