Rated for 1.3 A continuous current, it handles moderate power rails without saturating the ferrite material. ## 0402 footprint, active production Housed in the standard 0402 (1005 Metric) package — 1.00 mm x 0.55 mm, 0.55 mm seated height — this bead fits into any high-density PCB layout where board space is at a premium. The surface-mount termination is compatible with reflow soldering profiles for lead-free assemblies.","metaTitle":"BLM15EX221SN1D Murata Ferrite Bead, 220 Ohm @ 100MHz, 1.3A","metaDescription":"Murata BLM15EX221SN1D EMIFIL ferrite bead, 220 Ohm at 100 MHz, 1.3A, 0402 package.
