Product details

1 kOhm at 100 MHz — the suppression target

The BLM15HG102BH1D delivers 1 kOhms impedance at 100 MHz, the standard test frequency for conducted EMI suppression in the 100 MHz band where most clock harmonics and digital switching noise radiate. This is a signal-line ferrite bead, not a power-rail part — the 250 mA current rating and 1.1 Ohm DCR limit it to low-current supply or I/O filtering.

AEC-Q200 and the temperature envelope

Rated AEC-Q200, this part passed the automotive passive-component stress suite — thermal shock, moisture resistance, mechanical shock, and vibration. Active lifecycle status means no end-of-life risk for current designs — no PCN watch needed.

Frequently asked questions

What is the closest alternative to BLM15HG102BH1D in the BLM15H series?

The BLM15H series includes multiple impedance values at 100 MHz. The BLM15HG102BH1D is the 1 kOhm variant. A lower-impedance sibling (e.g., 600 Ohm or 120 Ohm) would pass more high-frequency content but drop less DC voltage across the DCR. The package, current rating, and AEC-Q200 qualification are shared across the series; the choice is the impedance target vs the allowable IR drop.

What compliance documentation does Murata provide for BLM15HG102BH1D?

As an AEC-Q200 qualified part, Murata provides a PPAP (Production Part Approval Process) package and a Certificate of Compliance upon request. The part is RoHS-compliant by Murata's standard material declaration. No separate UL or IEC certification is listed for this ferrite bead; the AEC-Q200 qualification is the primary automotive-grade certification.
