The 450 mA current rating sets the continuous load it can carry without saturating the ferrite material — stay below this for the impedance curve to hold. ## Temperature grade and package The 0402 (1005 metric) footprint is standard for high-density PCB layouts — the 0.55 mm seated height fits under low-profile shielding cans or between closely stacked boards.","metaTitle":"BLM15AG221SN1D Murata Ferrite Bead, 220 Ohm @ 100 MHz, 0402","metaDescription":"Murata BLM15AG221SN1D ferrite bead, 220 Ohm impedance at 100 MHz, 450 mA rating, 0402 package.
