Suppression on a signal line
The BLM15BX182SN1D is a single-line ferrite bead from Murata's EMIFIL® BLM15 series, delivering 1.8 kOhms impedance at 100 MHz to knock down conducted EMI on a signal or low-power rail.
0402 package and rework
In the 0402 (1005 metric) footprint, this bead is small enough to squeeze into dense filter banks near a connector or IC pin. The 0.55 mm seated height keeps it below low-profile shielding cans. Under a hot-air station the 0402 body heats fast and reflows cleanly — the nickel-barrier terminations handle the thermal cycle without cracking. Pin 1 orientation is irrelevant on a two-terminal part, but the marking stripe on the body confirms the orientation if the layout has a preferred pad.
