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.
The BLM15BB221SN1D provides 220 Ohms of impedance at 100 MHz, which is the standard reference frequency for ferrite bead attenuation in signal-line filtering applications.
The maximum continuous DC current rating is 200 mA, limited by the 800 mOhm DC resistance which governs self-heating at full load.
