BLM21PG221SN1D

by muRata(村田)

For high-frequency noise suppression along a PCB power path, the Murata BLM21PG221SN1D is a surface-mount ferrite bead in an 0805 package. Ferrite beads introduce frequency-dependent impedance, making them useful when separating a noisy supply path from circuitry that needs filtering. The supplied record identifies the package and library assets without specifying electrical ratings, so selection still requires checking the intended operating conditions. Its free KiCad package contains a two-pin symbol, the two-pad L0805 footprint and a 3D model. This conversion has seen use by 1 ProtoFlow engineer in real designs.
