BLM18KG260WH1D

Chip Ferrite Bead Overview

The Murata BLM18KG260WH1D is a single ferrite bead in the EMIFIL BLM18KG series, designed for automotive electronics under AEC-Q200 qualification. It features a 0603 (1608 metric) SMD package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height. The component provides an impedance of 26 Ohms at 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 2 A and has a maximum DC resistance of 32 mOhms. The operating temperature range spans from -55°C to +150°C.

Chip Ferrite Bead Feature Summary

• AEC-Q200 qualified for automotive reliability
• High current handling capability up to 2 A
• Low DC resistance for minimal power loss
• Compact 0603 surface mount footprint

Chip Ferrite Bead Applications

• Automotive electronic circuits
• Power line noise suppression
• DC-DC converter output filtering

Chip Ferrite Bead Procurement Notes

Verify the specific suffix WH1D against official Murata documentation to confirm package and termination specifications. Ensure the procurement source provides valid RoHS compliance data and confirms AEC-Q200 certification status for automotive applications. Cross-reference the impedance value at 100 MHz to match circuit requirements.

Chip Ferrite Bead Selection Notes

Select this component when high current capacity is required alongside moderate noise suppression in compact spaces. The 26 Ohm impedance offers a balance between attenuation and DC voltage drop. Verify that the 2 A current rating exceeds the peak operational current of the target power line to prevent saturation or overheating.

Chip Ferrite Bead Part Context

This part belongs to the Murata EMIFIL BLM18KG series, which focuses on high-current applications within the standard 0603 form factor. The KG series distinguishes itself by supporting higher amperage compared to standard signal-line ferrites, making it suitable for power distribution networks in automotive environments.

Chip Ferrite Bead Replacement Considerations

Check for other BLM18KG variants with similar impedance and current ratings. Confirm that any substitute maintains the same AEC-Q200 qualification and physical dimensions for direct board replacement.
