The 0402 (1005 Metric) footprint is the smallest common size for ferrite beads — it fits tight decoupling layouts near the IC power pin, but the 0.55 mm seated height means the pick-and-place nozzle clearance and solder-paste stencil aperture need to match the 0.5 A current path.","metaTitle":"Murata BLM15AG121SH1D Ferrite Bead, 120 Ohm @ 100 MHz","metaDescription":"Murata BLM15AG121SH1D EMIFIL ferrite bead, 120 Ohm impedance at 100 MHz, 500 mA rating, AEC-Q200 qualified, 0402 package.
