Filter performance and board-level fit
The BLM15HD182SZ1D is a Murata BLM15H series signal line ferrite bead in the 0402 (1005 Metric) package, delivering 1.8 kOhms impedance at 100 MHz to suppress conducted EMI on a single signal line. Rated for 200 mA continuous current with a maximum DC resistance of 2.2 Ohm, the voltage drop across the bead at full load is 440 mV — a factor to budget in low-voltage supply rails where the IR drop eats into the noise margin.
Automotive qualification and temperature envelope
AEC-Q200 qualified, this bead meets the passive-component stress test regimen for automotive electronics — thermal shock, solder heat resistance, and vibration endurance are verified per the standard.
