BLM18SG260TN1D

Chip Ferrite Bead Overview

The Murata BLM18SG260TN1D is a single-line ferrite chip bead in a 0603 (1608 metric) surface-mount package. It provides an impedance of 26 Ohms at 100 MHz with a 25% tolerance. The component supports a maximum DC current of 6 A and has a maximum DC resistance of 7 mOhms. It operates within a temperature range of -55°C to +125°C and meets AEC-Q200 automotive qualification standards.

Chip Ferrite Bead Feature Summary

• Designed for high-current power line applications due to low DC resistance
• Suppresses high-frequency electromagnetic interference noise
• Automotive-grade reliability certified under AEC-Q200

Chip Ferrite Bead Applications

• High-current power supply filtering
• Automotive electronic circuit noise suppression
• DC-DC converter output filtering

Chip Ferrite Bead Procurement Notes

Verify the specific suffix TN1D against official Murata documentation to confirm packaging and tape specifications. Ensure the procurement channel sources genuine components from authorized distributors to guarantee compliance with RoHS directives and AEC-Q200 automotive quality standards.

Chip Ferrite Bead Selection Notes

Select this component when a 26 Ohm impedance at 100 MHz is required alongside a high current rating of 6 Amperes. The 0603 footprint is suitable for space-constrained designs, while the low DC resistance minimizes power loss in high-current paths compared to higher-impedance alternatives.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM18S series, which specializes in EMIFIL chip ferrite beads for suppressing high-frequency noise in power lines. The series is engineered to handle large rated currents, making it distinct from standard signal-line ferrite beads that typically support lower current levels.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other Murata parts within the BLM18S series sharing identical electrical parameters and package dimensions, such as variants with different impedance values if system requirements change.
