BLM21BD221SN1D Description

Short technical summary and product information.

The BLM21BD221SN1D is a chip ferrite bead manufactured by Murata. It is designed as a signal line filter with a single line and provides 220 Ω impedance at 100 MHz. The component is housed in an 0805 (2012 metric) surface-mount package measuring 2.00 mm by 1.25 mm with a maximum height of 1.45 mm.

 

Electrical specifications include a maximum DC resistance of 250 mΩ and a maximum current rating of 350 mA, allowing use in circuits with moderate current demands. The operating temperature range spans from -55°C to 125°C, supporting a wide variety of environments. The storage temperature range is identical.

 

This ferrite bead is suitable for consumer and industrial equipment where high-frequency noise suppression is required. Common uses include filtering power supply lines and signal lines in compact electronic devices. The surface-mount configuration enables high-density PCB layouts and automated assembly.
