Product details

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.

Surface-mount 0402 package — standard pick-and-place, reflow soldering.

Frequently asked questions

What is the impedance of BLM15AX100SN1D and at what frequency?

10 Ohms at 100 MHz. This is a relatively low impedance — it provides mild filtering for high-frequency noise, not a heavy notch. Use it where you need to clean up a few dB of hash on signal lines or low-current power rails without significant signal degradation.

What is the current rating and DC resistance of this ferrite bead?

Rated for 1.74 A continuous current with a maximum DC resistance of 15 mOhm. The low DCR means minimal voltage drop and self-heating, so it can sit on a power rail feeding a small module without thermal concerns.
