BLM21HE601SH1L

Chip Ferrite Bead Overview

The Murata BLM21HE601SH1L is a surface-mount ferrite bead from the POWRTRN series, designed for high-current signal line applications. It features a 0805 (2012 metric) package with dimensions of 2.00mm x 1.25mm x 1.45mm. The component provides an impedance of 600 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 2.3A and has a maximum DC resistance of 55 mOhms. Rated for operation between -55°C and +125°C, it meets AEC-Q200 automotive qualification standards.

Chip Ferrite Bead Feature Summary

• High current handling capability suitable for power supply filtering
• Automotive grade reliability certified to AEC-Q200 standards
• Compact 0805 footprint optimized for dense PCB layouts

Chip Ferrite Bead Applications

• Automotive electronic systems requiring EMI suppression
• High-current signal line noise reduction
• Power supply input/output filtering in compact devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SH1L against official Murata documentation to confirm package and termination specifications. Ensure the selected variant matches the required 0805 form factor and 2.3A current rating for the target application. Cross-reference datasheets for precise impedance curves and thermal characteristics before finalizing procurement.

Chip Ferrite Bead Selection Notes

Select this component when high current capacity is critical alongside EMI suppression. The 2.3A rating distinguishes it from standard low-current ferrite beads. Verify that the 600 Ohm impedance at 100 MHz aligns with the noise spectrum of the circuit. Consider the 55 mOhms DC resistance impact on voltage drop in power paths.

Chip Ferrite Bead Part Context

This part belongs to the BLM21 series, specifically the POWRTRN sub-series focused on high-current performance. It shares the 0805 mechanical outline with other BLM21 variants but differs in magnetic material composition to support higher saturation currents. It complements lower-current models like the BLM21HG series by offering robust power integrity.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other Murata BLM21HE601 variants with identical electrical parameters. Verify pin compatibility and impedance tolerance if replacing with non-Murata brands. Ensure any alternative maintains the AEC-Q200 qualification if used in automotive contexts.
