The 300 mA continuous current rating and 350 mOhm max DCR set the DC voltage drop and self-heating; at full rated current the bead drops about 105 mV and dissipates roughly 32 mW, well within the 0402 body's thermal budget for most signal-line applications. ## 0402 footprint, single-line — tight-layout fit It is a single-line filter, so each bead cleans one signal trace — no shared suppression across multiple nets. The surface-mount termination suits standard reflow profiles; the tape-and-reel packaging is the usual pick-and-place format. No AEC-Q grade is stated in the record, but the temperature envelope alone does not guarantee automotive qualification — check the full Murata qualification report if the application requires PPAP-level data.","metaTitle":"BLM15BB470SN1D Murata 47 Ohm Ferrite Bead, 300 mA, 0402","metaDescription":"Murata BLM15BB470SN1D ferrite bead, 47 Ohms @ 100 MHz, 300 mA, 350 mOhm DCR, 0402 SMD.
