The Murata BLM15HB221SN1D is a single-line ferrite bead from the EMIFIL® BLM15 series, delivering 220 Ohms of impedance at 100 MHz in a 0402 (1005 Metric) chip package.
The EMIFIL® BLM15 series is a mature, widely used product family.
The BLM15HB221SN1D provides 220 Ohms of impedance at 100 MHz, which is the standard reference frequency for ferrite bead attenuation on signal lines.
The BLM15HB221SN1D is specified as a Signal Line filter, not a power rail ferrite bead. The 250 mA current rating and 1 Ohm DCR limit its use to low-current signal paths such as digital I/O, clock lines, or communication buses.
