BLM18KG102SN1D

Chip Ferrite Bead Overview

The Murata BLM18KG102SN1D is a single-channel ferrite chip bead in the BLM18KG series, designed for surface-mount assembly in a 0603 (1608 metric) package measuring 1.6 mm x 0.8 mm x 0.95 mm. It provides an impedance of 1 kOhms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 1 A and features a maximum DC resistance of 200 mOhms. It operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides high-frequency noise suppression for power lines without requiring a ground connection.
• Features a nickel barrier structure on external electrodes to ensure excellent soldering heat resistance.
• Designed to minimize resonance risks, thereby preserving signal waveform integrity.

Chip Ferrite Bead Applications

• Noise suppression in portable electronic devices
• Electromagnetic interference filtering in industrial equipment
• Power line filtering in consumer electronics

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against official Murata documentation to confirm packaging details and compliance status. Ensure the selected variant matches the required 0603 footprint and electrical specifications for the target circuit design before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when a low-profile 0603 ferrite bead is required for power line noise attenuation. The 1 A current rating and 200 mOhm DCR make it suitable for applications where moderate current handling and minimal voltage drop are necessary alongside effective high-frequency filtering.

Chip Ferrite Bead Part Context

This part belongs to the BLM18_xN family of EMIFIL chip ferrite beads. These components are engineered for general-purpose EMI suppression in compact electronic designs. The BLM18KG variant specifically targets power line applications, offering a balance of impedance performance and current capacity within standard surface-mount dimensions.

Chip Ferrite Bead Replacement Considerations

Consult official Murata substitution guides for verified equivalents. Cross-referencing with other BLM18 series parts requires careful validation of impedance curves and current ratings to ensure functional compatibility.
