BLM18TG601TN1D

Chip Ferrite Bead Overview

The Murata BLM18TG601TN1D is a single-channel surface-mount ferrite bead designed for EMI suppression in the 0603 (1608 metric) package. It exhibits an impedance of 600 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current rating of 200 mA and has a maximum DC resistance of 450 mOhms. It operates within a temperature range of -55°C to +125°C, with physical dimensions of 1.6 mm length, 0.8 mm width, and 0.95 mm height.

Chip Ferrite Bead Feature Summary

• Provides effective electromagnetic interference suppression through high-impedance characteristics at target frequencies.
• Utilizes a compact 0603 surface-mount footprint suitable for space-constrained printed circuit board layouts.
• Constructed with ferrite and steel materials to ensure stable performance across specified operating temperatures.

Chip Ferrite Bead Applications

• General-purpose EMI noise filtering in electronic circuits
• Signal line protection in consumer electronics
• Power supply input/output decoupling

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'TN1D' against official Murata documentation to confirm material composition and termination specifications. Ensure the selected variant matches the required 200 mA current rating and 600 Ohm impedance profile for the intended application frequency. Cross-reference package dimensions to confirm compatibility with automated placement equipment.

Chip Ferrite Bead Selection Notes

Select this component when a 0603 form factor is required for high-frequency noise attenuation. Compare the 200 mA current limit against peak circuit loads to prevent saturation. Evaluate the 450 mOhms DC resistance impact on voltage drop relative to other series options like BLM18SP or BLM18AG if higher current capacity is needed.

Chip Ferrite Bead Part Context

This part belongs to the EMIFIL BLM18TG series, which utilizes ferrite and steel composite materials. This material selection distinguishes it from standard ferrite-only beads, offering specific magnetic properties suited for particular EMI suppression environments within the broader Murata chip bead portfolio.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include BLM18TG601SN1D, which shares the same series and electrical parameters but may differ in packaging or termination details. Verify equivalent impedance and current ratings before substitution.
