BLM21BD272SN1L Description

Short technical summary and product information.

The Murata BLM21BD272SN1L is a single-line ferrite bead designed for signal line filtering. It provides a nominal impedance of 2.7 kOhm at 100 MHz, making it effective for suppressing high-frequency noise. The component is rated for a maximum DC current of 200mA and has a maximum DC resistance of 800mOhm.

 

This ferrite bead is housed in an 0805 (2012 Metric) surface-mount package with a maximum height of 1.45mm. It operates over a temperature range of -55°C to 125°C, suitable for a wide variety of environments. The component is designed for surface mount assembly and is available in tape and reel packaging (details not verified).

 

Typical applications include noise suppression in signal lines of consumer electronics, industrial equipment, and medical devices (as per the BLM21 series reference specification). The high impedance at 100 MHz helps attenuate unwanted EMI while allowing the desired signal to pass with minimal attenuation.
