Product details

220 Ohm suppression at 100 MHz, 450 mA continuous

The Murata BLM15BX221SN1D is a single-line ferrite bead from the EMIFIL® BLM15 series, delivering 220 Ohms impedance at 100 MHz to suppress conducted noise on signal lines. Rated for 450 mA continuous current with a maximum DC resistance of 270 mOhm — the DCR limits the voltage drop and self-heating at the rated current, so a 450 mA load sees roughly 122 mV drop across the bead.
