10 Ω at 100 MHz, 1 A continuous — the suppression window
The BLM15AG100SH1D is a single-line ferrite bead from Murata's EMIFIL® BLM15 series, in a standard 0402 (1005 Metric) surface-mount package. Its 10 Ω impedance at 100 MHz targets conducted noise in the 30–300 MHz range — the band where clock harmonics and switching-regulator edges radiate most readily.
AEC-Q200 qualification and the operating envelope
AEC-Q200 qualification certifies this bead for automotive-grade stress — thermal shock, moisture resistance, mechanical shock, and vibration per the passive-component stress test standard.
