BLM18HK601SN1D

Chip Ferrite Bead Overview

The BLM18HK601SN1D is a single-line ferrite chip bead from the Murata EMIFIL BLM18H_SN series. It features a 0603 (1608 metric) surface-mount package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height. The component provides an impedance of 600 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 100 mA and has a maximum DC resistance of 900 mOhms. The operating temperature range spans from -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides high impedance noise suppression for digital interface circuits
• Optimized for compact surface-mount applications in small form factors
• Designed for stable performance across wide industrial temperature ranges

Chip Ferrite Bead Applications

• Digital interface noise suppression
• Power line filtering
• General-purpose EMI suppression in portable devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against the official Murata datasheet to confirm packaging type and tape/reel specifications. Ensure the selected variant matches the required 100 mA current rating and 900 mOhm DCR limits for the target circuit design. Cross-reference the RoHS status and MSL classification during procurement planning.

Chip Ferrite Bead Selection Notes

Select this component when a 600 Ohm impedance at 100 MHz is required within a 0603 footprint. The 100 mA current rating suits low-power signal lines rather than high-current power rails. Compare against the BLM18HG and BLM18KG series if higher current handling or lower DC resistance is necessary for the application.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM18H_SN series of ferrite beads. It is distinct from the BLM18HG and BLM18KG series, which offer different current ratings and DC resistance values while maintaining similar impedance characteristics. The BLM18HK variant specifically targets applications requiring moderate current capacity with standard noise attenuation profiles.
