BLM21RK102SN1D Description

Short technical summary and product information.

The BLM21RK102SN1D is a ferrite bead from Murata, designed for noise suppression in electronic circuits. It offers a nominal impedance of 1 kOhm at 100 MHz, making it suitable for filtering high-frequency noise on power and signal lines. This component has a maximum DC resistance of 500 mOhm and a maximum current rating of 200 mA, ensuring low power loss in moderate current applications.

 

The ferrite bead is housed in a standard 0805 (2012 Metric) surface-mount package, with dimensions of 2.00 mm length, 1.25 mm width, and a maximum height of 1.05 mm. It is designed for surface mount assembly and operates over a wide temperature range of -55°C to 125°C, making it suitable for both consumer and industrial environments.

 

This component is a single-line ferrite bead, typically used in power supply filtering, DC-DC converter output filtering, and signal line noise suppression where a 1 kOhm impedance at 100 MHz is required. The package is compatible with automated pick-and-place assembly processes.
