Product details

1 kOhm at 100 MHz, 250 mA — the signal-line filter for automotive-grade noise

The BLM15HG102SH1D is a single-line ferrite bead from Murata's EMIFIL® BLM15 series, housed in an 0402 (1005 Metric) surface-mount package. It delivers 1 kOhms impedance at 100 MHz, rated for 250 mA continuous current with a maximum DC resistance of 1.1 Ohm. The 1 kOhm impedance at 100 MHz is the suppression sweet spot for conducted EMI on digital signal lines, power rails, or I/O traces — it knocks down the common-mode noise peak without attenuating the DC or low-frequency signal content.

Rated AEC-Q200, this bead is qualified for automotive-grade stress — thermal shock, humidity bias, and vibration per the passive-component qualification standard. The BLM15HG102SH1D is a current-design-in part for automotive and industrial signal-line filtering.

Sourcing and compliance posture

The part carries the standard Murata EMIFIL® compliance documentation (RoHS, REACH, and AEC-Q200 test reports available on request).

Frequently asked questions

What is BLM15HG102SH1D's impedance at 100 MHz?

It is 1 kOhms at 100 MHz, the standard test frequency for ferrite bead impedance. This value tells you the suppression level for conducted EMI in the 100 MHz band — higher impedance means more attenuation.

Is BLM15HG102SH1D AEC-Q200 qualified?

Yes, it carries an AEC-Q200 rating, meaning it meets the automotive passive-component qualification for temperature cycling, moisture resistance, and mechanical shock. Suitable for engine bay and cabin electronics.
