BLM18KG601WH1D

Chip Ferrite Bead Overview

The Murata BLM18KG601WH1D is a 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 A and features a maximum DC resistance of 90 mOhms. 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

• AEC-Q200 qualified for automotive reliability requirements
• High current handling capability up to 1 A
• Glue-only mounting specification for secure attachment

Chip Ferrite Bead Applications

• Automotive power distribution networks
• Noise suppression in high-current DC lines
• Embedded system power filtering

Chip Ferrite Bead Procurement Notes

Verify that the specific suffix WH1D corresponds to the glue-only mounting requirement, as this affects assembly processes. Confirm the 1 A current rating aligns with the target circuit's peak load conditions. Ensure the 0603 footprint matches the PCB design constraints. Cross-reference the AEC-Q200 certification status if automotive compliance is mandatory for the end product.

Chip Ferrite Bead Selection Notes

Select this component when high current capacity is required alongside significant noise attenuation at 100 MHz. The 0603 package offers space efficiency compared to larger footprints. Consider the glue-only constraint during layout planning to ensure proper mechanical fixation. Compare against lower current variants if the application does not require the full 1 A rating.

Chip Ferrite Bead Part Context

This part belongs to the BLM18 series of ferrite beads from Murata Electronics. The series includes various impedance and current ratings within the 0603 form factor. The KG suffix typically denotes specific material characteristics optimized for high-current applications. This model represents a specialized variant designed for robust performance in demanding environments.

Chip Ferrite Bead Replacement Considerations

BLM18HD601SH1D offers similar impedance but lower current handling. BLM18AG601SN1D provides comparable specifications with different packaging options. Verify current ratings and mounting requirements before substitution.
