Description
BLM18KG471SN1D is a Murata ferrite-bead EMI filter (single-line) from the BLM series. Key points:
- 471 = about 470 Ω impedance at 100 MHz, providing RF noise suppression.
- Very low DC resistance, so it minimally affects the power or signal line.
- Comes in a small surface-mount package (BLM18K family); SN1D is Murata’s suffix for its variant/packaging.
- Used in series with a line (power or signal) to attenuate high-frequency noise without impacting DC or low-frequency signals.
- Typical applications: DC rails, USB/HDMI/data lines, wireless modules, automotive electronics.
For exact dimensions, current rating, and electrical specs, consult the Murata BLM18KG471SN1D datasheet.

Equivalent
BLM18KG471SN1D is a 0603 ferrite bead (470 Ω @100 MHz). Equivalent products are any 0603/1608-metric EMI ferrite bead with the same impedance (≈470 Ω at 100 MHz), equal or higher DC current rating and similar DC resistance. Look for matching parts from TDK, Yageo, Taiyo Yuden or Murata (same specs). Always verify with datasheets for size, impedance curve, rated current and DC resistance before substituting.
