0402 ferrite bead for signal-line EMI suppression
The Murata BLM15HD182BH1D is a single-line ferrite bead in the BLM series, delivering 1.8 kOhms impedance at 100 MHz. That impedance peak targets conducted noise in the VHF band—common on clock lines, data buses, and power rails where a clean signal floor matters. Rated for 200 mA continuous current with a 2 Ohm max DC resistance, the bead drops about 0.4 V at full load. The 0402 footprint (1.00 mm x 0.50 mm) fits tight signal-line layouts where board real estate is at a premium.
AEC-Q200 qualification and operating range
AEC-Q200 qualified, this bead is stress-tested for automotive-grade reliability—thermal shock, moisture resistance, and vibration per the standard. The -55°C to 150°C operating range covers under-hood and engine-bay temperature extremes without derating. Production status is active per Murata's current lifecycle record.
