1 kOhm at 100 MHz, 350 mA continuous
The BLM15AX102SZ1D is a single-line ferrite bead from Murata's BLM series, offering 1 kOhm impedance at 100 MHz — the frequency where conducted EMI from switching regulators and digital clocks typically peaks. Rated for 350 mA continuous current, it handles low-power supply rails and signal lines without saturating the ferrite material.
AEC-Q200 and the 125 °C ceiling
Rated AEC-Q200, this bead is qualified for automotive-grade stress — thermal shock, vibration, and solder heat resistance per the AEC-Q200 passive-component standard. The operating range spans -55 °C to 125 °C, covering under-hood and engine-bay ambient where the bead sits on a PCB near the ECU or a power module.
0402 footprint, tape-and-reel delivery
Housed in the standard 0402 (1005 Metric) package — 1.00 mm x 0.55 mm, seated height 0.55 mm max. Supplied on tape and reel (Cut Tape also available), compatible with high-speed pick-and-place. The single-line topology means it filters one power or signal trace per component; use one per rail or per I/O line.
