220 Ohm suppression at 100 MHz
The BLM15BB221SH1D is a single-line ferrite bead from Murata's EMIFIL BLM15 series, delivering 220 Ohms of impedance at 100 MHz. This is the figure that governs its noise-suppression performance on a power rail or signal line — the bead presents a resistive loss at the target frequency, dissipating conducted EMI as heat rather than reflecting it back into the circuit. The single-line configuration means one bead per net — no shared suppression across multiple traces.
Active lifecycle, no EOL watch
Marked as Active by Murata, the BLM15BB221SH1D carries no end-of-life notice. For a BOM line that uses this bead, there is no near-term obsolescence risk — it remains a standard catalog item available through distribution.
