The trade-off is a 410 mOhm DC resistance at the 350 mA current rating; at full rated current the voltage drop is about 144 mV and the self-heating adds roughly 50 mW, which is negligible in most layouts but worth checking if the trace feeds a low-voltage rail. Above that current the ferrite saturates and the impedance collapses, so don't use it on a main power bus pulling 500 mA. ## 0402 footprint and board integration Housed in a standard 0402 (1005 metric) package, the BLM15BX471SN1D measures 1.00 mm x 0.55 mm with a 0.55 mm max seated height. That low profile fits under shielding cans or between closely spaced components on a dense PCB. The single-line configuration means one bead per filtered trace — no shared suppression across multiple lines. Surface-mount assembly with tape-and-reel packaging — standard pick-and-place, no special handling.","metaTitle":"Murata BLM15BX471SN1D Ferrite Bead, 470 Ohm @ 100 MHz","metaDescription":"Murata BLM15BX471SN1D EMIFIL ferrite bead, 470 Ohm impedance at 100 MHz, 350 mA rated current, 0402 package.
