BLM18KG221SH1D Description

Short technical summary and product information.

The Murata BLM18KG221SH1D is a chip ferrite bead designed for DC power line filtering in automotive electronics. It offers a nominal impedance of 220 Ω at 100 MHz with ±25% tolerance, providing effective noise suppression. The component features a maximum DC resistance of 50 mΩ (initial) and 60 mΩ after testing, ensuring low power loss. Rated current is 2.2 A at 85°C ambient temperature and 1.5 A at 125°C, making it suitable for high-temperature environments. The bead is housed in a 0603 (1608 metric) surface-mount package with a maximum height of 0.95 mm. It operates over a temperature range of -55°C to +125°C and is qualified to AEC-Q200 for automotive reliability. ESD rating is 2 kV. This part is supplied in tape and reel packaging.
