Parametric fit for signal-line filtering
The BLM15GG221SN1D is a single-line ferrite bead from Murata's EMIFIL® BLM15 series, offering 220 Ohms impedance at 100 MHz — a common suppression target for conducted EMI on power rails or low-speed digital lines in the 10-100 MHz band. Rated for 300 mA continuous current with a maximum DC resistance of 700 mOhm, the voltage drop across the bead at full rated current is 210 mV — a factor to budget in low-voltage supply rails where headroom is tight.
