The 0402 footprint (1.00 mm × 0.55 mm) and 0.55 mm seated height fit tight layouts near the IC supply pin — place it as close to the load as possible so the trace between bead and pin does not re-radiate the noise you just filtered. ## NRND — plan the BOM migration now Existing production can continue through independent distribution, but new board spins should evaluate the current-generation EMIFIL® part with the same 0402 footprint and 220 Ω @ 100 MHz target. ## Temperature range and board fit The 0402 package reflows with standard lead-free profiles; the ferrite body does not crack under thermal shock if the pad geometry follows the manufacturer's land pattern.","metaTitle":"Murata BLM15EG221SN1D Ferrite Bead, 220 Ω @ 100 MHz, 700 mA","metaDescription":"Murata BLM15EG221SN1D EMIFIL ferrite bead, 220 Ω impedance at 100 MHz, 700 mA rating, 0402 package.
