BLM18SG121TN1D Description

Short technical summary and product information.

The Murata BLM18SG121TN1D is a chip ferrite bead designed for power line filtering in consumer and industrial equipment. It offers a typical impedance of 120 Ω at 100 MHz, with a maximum DC resistance of 25 mΩ and a current rating of 3 A.

 

This single-line ferrite bead is housed in a compact 0603 (1608 metric) surface-mount package measuring 1.60 mm x 0.80 mm x 0.65 mm. It operates over a wide temperature range from -55°C to +125°C, making it suitable for demanding environments.

 

The component is part of Murata's BLM18 series and is intended for applications where suppression of high-frequency noise on power lines is required. Its low DCR minimizes power loss, while the high current rating supports moderate power delivery.
