BLM21BB121SN1D Description

Short technical summary and product information.

The Murata BLM21BB121SN1D is a single-line chip ferrite bead designed for signal line filtering applications. It offers a nominal impedance of 120 Ω at 100 MHz, with a maximum DC resistance of 190 mOhm and a maximum current rating of 600 mA.

 

This ferrite bead is housed in a standard 0805 (2012 metric) surface-mount package, measuring 2.00 mm x 1.25 mm with a maximum height of 1.05 mm. It operates over a wide temperature range of -55°C to 125°C, making it suitable for demanding environments.

 

The component is intended for use in consumer and industrial equipment where suppression of high-frequency noise on signal lines is required. Its compact footprint and surface-mount design facilitate automated assembly in high-volume production.
