33 Ω at 100 MHz, 300 mA continuous
The Murata Electronics BLM15BA330SN1D is a single-line signal ferrite bead from the EMIFIL® BLM15 series, offering 33 Ohms impedance at 100 MHz with a 300 mA current rating and 400 mOhm max DCR. The 33 Ω peak at 100 MHz targets conducted noise in the HF band — typical for suppressing ripple from a DC-DC converter or clock-line harmonics on a signal trace.
