BLM18GG471SN1D

Chip Ferrite Bead Overview

The Murata BLM18GG471SN1D is a single ferrite chip bead from the EMIFIL BLM18G series, designed for surface mount technology in a 0603 (1608 metric) package. It provides an impedance of 470 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 exhibits a maximum DC resistance of 1.3 Ohms. It operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides high impedance attenuation for electromagnetic interference suppression in compact surface-mount layouts
• Engineered for stable performance across wide industrial temperature variations
• Features low DC resistance to minimize signal loss in power or data lines

Chip Ferrite Bead Applications

• EMI suppression filters
• Digital interface circuits

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against official Murata documentation to confirm packaging and terminal specifications. Ensure the selected variant matches the required current rating and impedance tolerance for the target circuit design before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when a 0603 footprint is constrained but higher current handling than lower-rated series is unnecessary. Compare against the BLM18HK series if higher current capacity is required, or the BLM18PG series for different resistance characteristics while maintaining similar impedance profiles.

Chip Ferrite Bead Part Context

This part belongs to the Murata EMIFIL BLM18G series of ferrite beads. These components are widely used in consumer electronics and industrial equipment for noise reduction. The 0603 size offers a balance between physical space savings and electrical performance for general-purpose filtering applications.

Chip Ferrite Bead Replacement Considerations

BLM18HK471SN1D: Higher current rating (200mA vs 1.5A in other series, check datasheet for exact comparison). BLM18PG471SN1D: Similar impedance but different DC resistance and current ratings.
