BLM18KG601SH1D

Chip Ferrite Bead Overview

The Murata BLM18KG601SH1D is a single-line ferrite chip bead in a 0603 (1608 metric) surface-mount package. It provides an impedance of 600 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 1.3 A and has a maximum DC resistance of 0.15 Ohms. It operates within a temperature range of -55°C to +125°C and meets the AEC-Q200 automotive qualification standard.

Chip Ferrite Bead Feature Summary

• High current handling capability suitable for power line noise suppression
• Automotive-grade reliability certified under AEC-Q200 standards
• Compact 0603 footprint designed for dense surface-mount layouts

Chip Ferrite Bead Applications

• Automotive electronic systems requiring EMI suppression
• Power supply output filtering in compact devices
• Noise reduction on high-current signal lines

Chip Ferrite Bead Procurement Notes

Verify the specific suffix against official Murata documentation to confirm physical dimensions and electrical tolerances, as variations exist within the BLM18 family. Ensure the selected variant matches the required current rating and impedance characteristics for the target circuit design before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when a 0603 ferrite bead must handle up to 1.3 A while providing 600 Ohms of impedance at 100 MHz. Consider the low DC resistance of 0.15 Ohms to minimize voltage drop in power paths. Confirm that the AEC-Q200 qualification aligns with automotive or high-reliability application requirements.

Chip Ferrite Bead Part Context

This part belongs to the Murata EMIFIL BLM18 series of ferrite beads. The series offers various impedance and current ratings in standardized packages. The BLM18KG variant specifically targets applications needing higher current capacity compared to lower-rated siblings in the same form factor.

Chip Ferrite Bead Replacement Considerations

BLM18AG601SN1D: Lower current rating (500 mA). BLM18HD601SH1D: Lower current rating (100 mA). BLM18SP601SZ1D: Higher current rating (1.5 A) but different height.
