Product details

10 Ω at 100 MHz, 1.74 A — the low-DCR choice for power-line filtering

The BLM15AX100SZ1D is a single-line ferrite bead from Murata's BLM series, in the 0402 (1005 Metric) package. It delivers 10 Ω impedance at 100 MHz, with a 1.74 A continuous current rating and a maximum DC resistance of 15 mΩ.

AEC-Q200 — built for under-hood and chassis-mounted electronics

AEC-Q200 qualification means this ferrite bead passed the automotive-grade stress tests: thermal shock, moisture resistance, vibration, and solderability at the component level.

0402 footprint, 0.55 mm seated height — board-fit constraints

The 0402 body (1.00 mm x 0.50 mm) with a 0.55 mm max height fits tight card-edge or mezzanine gaps. Surface-mount assembly with standard reflow profile; the tape-and-reel packaging (Cut Tape or full reel) matches pick-and-place feeders.

Frequently asked questions

What is the closest alternative to BLM15AX100SZ1D in the BLM family?

Murata's BLM15AX series includes multiple impedance values at 100 MHz. The closest parametric peer shares the same 0402 package, AEC-Q200 rating, and 1.74 A current ceiling but with a different impedance target. The choice between them depends on the attenuation needed at the switching frequency — 10 Ω suits lower-frequency noise (<100 MHz), while higher-impedance variants (e.g., 100 Ω) are better for suppressing harmonics above 200 MHz.

What compliance documentation does Murata provide for BLM15AX100SZ1D?

Murata provides RoHS and REACH compliance declarations for the BLM15AX series. The AEC-Q200 qualification document covers the automotive-grade stress test results. No UL or IEC certification is listed for this ferrite bead — those standards apply to equipment-level safety, not passive component-level ratings.

Where can I buy BLM15AX100SZ1D?
