Murata BLM31KN801BH1L Chip Ferrite Bead

The Murata BLM31KN801BH1L is a surface mount chip ferrite bead designed to minimize noise and distortion in electronic circuits. Its unique design allows it to function nearly as a resistor at noise frequencies, reducing resonance potential. The nickel barrier structure of the external electrodes provides excellent solder heat resistance, and its low DC resistance makes it suitable for high-current applications, up to a maximum of 4A DC. It is commonly used in automotive powertrain and safety systems and is rated for an operating temperature range of -55°C to 150°C.
