The Murata BLM31KN471BH1L is a chip ferrite bead designed for noise suppression in a variety of applications. Its unique design minimizes resonance and distortion of signal waveforms, even in circuits with unstable ground lines. The nickel barrier structure ensures excellent solder heat resistance, and its low DC resistance allows for use in high-current circuits up to 4A DC. This component is particularly well-suited for automotive powertrain and safety systems, and is rated for operation up to 150°C. Always consult the latest datasheet for detailed specifications and ordering information.
