BLM18KG260TN1D

Chip Ferrite Bead Overview

The Murata BLM18KG260TN1D is a single-line ferrite chip bead in an EIA 0603 (1.6mm x 0.8mm) surface-mount package. It provides an impedance of 26 Ohms at 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 6 A and features a low maximum DC resistance of 7 mOhms. It operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification for automotive reliability.

Chip Ferrite Bead Feature Summary

• High current handling capability up to 6 A
• Low DC resistance for reduced power loss
• Compact 0603 footprint design

Chip Ferrite Bead Applications

• DC power line filtering for portable mobile equipment
• Noise suppression in cellular phone power circuits
• Filtering for notebook PC power supplies
• EMI suppression in hard disk drive systems

Chip Ferrite Bead Procurement Notes

Verify the specific suffix against official Murata documentation, as variations such as TH1D or TN1D may indicate differences in tape and reel packaging or manufacturing lot codes rather than functional changes. Confirm RoHS compliance status and ensure the selected variant matches the required reel quantity for automated assembly processes.

Chip Ferrite Bead Selection Notes

Select this component when high current capacity is required in a minimal 0603 space. The low DC resistance minimizes voltage drop and heat generation in power lines. Ensure the target noise frequency aligns with the 26 Ohm impedance peak at 100 MHz for effective attenuation.

Chip Ferrite Bead Part Context

This part belongs to the BLM18KG series, designed specifically for high-current applications. It offers improved performance over conventional 0603 beads by managing higher currents while maintaining a small physical size comparable to standard signal ferrites.

Chip Ferrite Bead Replacement Considerations

Cross-reference with other BLM18KG series variants for different impedance values. Verify that substitute parts maintain the same 6 A rating and 0603 dimensions to ensure mechanical compatibility.
