Description
BLM31KN271SH1L is a Murata BLM31 series surface-mount ferrite bead used for EMI/RFI suppression. The "271" denotes 270 Ω impedance at 100 MHz, providing high-frequency attenuation with low DC resistance. It’s intended for placing in series with power or signal lines to clean noise in portable electronics, consumer, automotive, and telecom circuits. The "SH1L" suffix encodes size, lead termination, and RoHS/compliant reflow packaging. Operating temperature typically −55 to +125°C (per datasheet) and it is suitable for surface-mount reflow soldering. For exact dimensions, current rating, and DC resistance, consult the Murata BLM31KN271SH1L datasheet.
Equivalent
Do you want cross-reference equivalents from other manufacturers for the same impedance (≈270 Ω at 100 MHz) and same footprint (likely 1206) as BLM31KN271SH1L? If yes, specify target vendors (TDK, Würth, Yageo, Vishay, etc.) and current rating. I’ll provide exact part numbers.
