The BLM15BB221SN1D is a single-line ferrite bead from Murata's EMIFIL® BLM15 series, delivering 220 Ohms of impedance at 100 MHz in a standard 0402 (1005 metric) surface-mount package. Rated for a maximum continuous current of 200 mA, with a DC resistance of 800 mOhm max — the DCR sets the voltage drop and self-heating at the rated current, so the 200 mA ceiling is the thermal limit, not the magnetic saturation point.
