BLM18EG121SN1D Description

Short technical summary and product information.

The Murata BLM18EG121SN1D is a single-line chip ferrite bead designed for noise suppression in consumer and industrial equipment. It offers a typical impedance of 120 Ω at 100 MHz, with a minimum impedance of 90 Ω at 1 GHz. The component is rated for a maximum DC current of 2 A and features a low DC resistance of 40 mΩ, minimizing power loss.

 

This ferrite bead is housed in a compact 0603 (1608 Metric) surface mount package, with dimensions of 1.60 mm x 0.80 mm and a maximum height of 0.95 mm. It operates over a wide temperature range of -55°C to +125°C, making it suitable for demanding environments. The part is supplied in tape and reel packaging for automated assembly.

 

Applications include power line filtering, signal line noise suppression, and EMI reduction in base stations, industrial robotics, medical equipment (GHTF Class A/B/C), and consumer electronics. The BLM18EG series is characterized by its high-frequency performance and reliability.
