BLM18KN_EH Automotive Ferrite Chip Beads Murata BLM18KN_EH Automotive Ferrite Chip Beads are ideal for noise suppression in power lines at temperatures up to +175°C. The BLM18KN_EH beads combine ferrite material that does not lose magnetic properties at high temperatures and an electrode to suppress temperature-related deterioration. Target applications are automotive equipment such as engine and transmission electronic control units (ECUs) and turbo motor controllers, with the components meeting AEC-Q200 qualification requirements. The BLM18KN_EH components help meet the design challenge of implementing direct power line noise suppression closer to the engine.
