Murata BLM18KN221EH1D Ferrite Bead

The BLM18KN221EH1D is a high-performance surface-mount chip ferrite bead designed for noise filtering in electronic circuits. It exhibits low DC resistance of 0.050 ohms and impedance of 2200 ohms at 100MHz, making it suitable for high-frequency applications. The device operates within a temperature range of -55°C to 175°C and supports a rated current of 1A at 150°C. Its compact 0603 size (1.6mm x 0.8mm x 0.8mm) ensures easy integration into dense circuit layouts. The ferrite bead provides effective noise suppression without requiring ground connection, and features excellent solder heat resistance up to 175°C, making it ideal for automotive and powertrain circuits.
