BLM18PG121SH1D Description

Short technical summary and product information.

The Murata BLM18PG121SH1D is a chip ferrite bead designed for DC power line filtering in automotive electronics. It provides a typical impedance of 120 Ohm at 100 MHz with ±25% tolerance, effectively suppressing high-frequency noise. With a maximum DC resistance of 50 mOhm, it minimizes power loss in the circuit. The component is rated for a continuous current of 2 A at an ambient temperature of 85°C, derating to 1 A at 125°C.

 

This ferrite bead operates over a wide temperature range of -55°C to 125°C, making it suitable for harsh automotive environments. It is AEC-Q200 qualified, ensuring reliability under stringent automotive stress tests. The part is housed in a standard 0603 (1608 Metric) surface mount package with a maximum height of 0.95 mm, allowing for compact PCB layouts. The single-line filter construction is optimized for power line applications where clean DC supply is critical.
