Below 10 MHz the bead acts as a low-resistance conductor (280 mOhm DCR max); above 100 MHz the impedance rolls off as the parasitic capacitance dominates. ## Current rating and DCR: the thermal budget trade-off Rated for 700 mA continuous current, the 280 mOhm DCR means a voltage drop of 196 mV at full load and 137 mW of self-heating. ## AEC-Q200 and the 0402 footprint: what the qualifications buy you AEC-Q200 qualification means this bead passed the automotive-grade stress tests: vibration, mechanical shock, solder heat resistance, and 1000-hour high-temperature operating life at 125 °C. The 0402 (1005 metric) package — 1.00 mm × 0.55 mm with a 0.55 mm seated height — fits the tight clearances of a camera module, ADAS ECU, or infotainment board where board space is the constraint, not the current draw. ## Active production and sourcing posture No direct functional replacement exists within the BLM15EG series at this impedance and current rating — the 221 impedance code (220 Ohms) is specific to this variant.","metaTitle":"Murata BLM15EG221SH1D 0402 Ferrite Bead, 220 Ohm @ 100 MHz","metaDescription":"Murata BLM15EG221SH1D ferrite bead, 0402 case, 220 Ohm impedance at 100 MHz, 700 mA rating, AEC-Q200 qualified.
