The BLM15BA050SN1D: Rated for 300 mA continuous current with a maximum DC resistance of 100 mOhm — the DCR sets the IR drop and self-heating in the signal path, so at 300 mA the voltage drop is 30 mV, negligible for most logic-level lines.
Impedance is 5 Ohms at 100 MHz — this is a low-impedance bead intended for high-frequency noise suppression on signal lines where the series resistance must stay low to avoid signal attenuation at DC.
