10 Ohm at 100 MHz — mild suppression for signal or low-current power rails
The BLM15AX100SN1D is a single-line ferrite bead from Murata's EMIFIL® BLM15 series, offering 10 Ohms impedance at 100 MHz. That is a gentle filtering action — it knocks down high-frequency noise without heavily attenuating the signal or power below 100 MHz. Think of it as a light snub for clock lines, I/O traces, or low-current supply rails where you just need to shave off a few dB of hash. Rated for 1.74 A continuous current with a maximum DC resistance of 15 mOhm, this bead handles power rail filtering without significant voltage drop or self-heating.
