BLM02BX121SN1D

Chip Ferrite Bead Overview

The Murata BLM02BX121SN1D is a single-line ferrite chip bead designed for surface-mount applications. It operates within the EMIFIL BLM02 series and utilizes a compact 01005 (0402 metric) package with dimensions of 0.40mm x 0.20mm x 0.22mm. The component provides an impedance of 120 Ohms at a test frequency of 100 MHz, with a tolerance of 25%. It supports a maximum DC current of 350 mA and exhibits a maximum DC resistance of 500 mOhms. The device functions reliably across a temperature range of -55°C to +125°C.

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against official Murata documentation to confirm packaging details and compliance status. Ensure the selected variant matches the required impedance and current ratings for the target circuit. Cross-reference datasheets for accurate handling and soldering parameters before integration.

Chip Ferrite Bead Selection Notes

Select this component when space is limited due to its 01005 package size. Evaluate the 350 mA current rating to ensure it meets the circuit's operational requirements without saturation. Consider the 120 Ohm impedance profile at 100 MHz for appropriate high-frequency attenuation needs in sensitive signal lines.
