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.
