The Murata BLM18KG121JH1D is a chip ferrite bead from the BLM18H series designed for automotive electronics. It provides a typical impedance of 120 Ω at 100 MHz with a tolerance of ±25%, making it suitable for suppressing high-frequency noise on DC power lines. The component is qualified to AEC-Q200 for reliable operation in automotive environments.
Electrically, the bead is rated for 1.9 A DC current at an ambient temperature of 125°C; at the maximum operating temperature of 150°C, the rated current is 10 mA. The maximum DC resistance is 30 mΩ initially, with a post-test limit of 40 mΩ as specified in the reference specification. It also features an ESD rating of 2 kV (Human Body Model), corresponding to ESD Rank 2.
The device is housed in a 0603 (1608 metric) surface-mount package with dimensions of 1.6 mm × 0.8 mm × 0.75 mm. It operates over the temperature range of -55°C to +150°C. As a single-line power line filter, it is suited for use in engine control units, body electronics, and other automotive subsystems requiring high-temperature performance.
