BLM18KG601SN1D

Chip Ferrite Bead Overview

The Murata BLM18KG601SN1D is a single-line ferrite chip bead in the EMIFIL BLM18KG series, designed for high-current power applications. It features a 0603 (1608 metric) surface-mount package with dimensions of 1.6 mm length, 0.8 mm width, and 0.95 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 rating of 1.3 A and has a maximum DC resistance of 150 mOhms. The device operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against official Murata documentation to confirm packaging details such as reel or cut tape configuration. Ensure the selected variant matches the required impedance tolerance and current rating for the target power application. Cross-reference the RoHS status and moisture sensitivity level with current manufacturing standards before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when high current capacity is required in a standard 0603 footprint. The BLM18KG series offers significantly higher rated current compared to conventional ferrite beads of the same size. Consider the low DC resistance benefit for efficiency-critical portable applications where power consumption must be minimized.

Chip Ferrite Bead Part Context

This part belongs to the Murata EMIFIL BLM18KG series, which introduces enhanced high-current performance for EIA 0603 sized ferrite beads. The series is engineered to replace larger 0805 and 1206 components while maintaining effective noise suppression. It targets modern portable electronics requiring efficient power management and compact form factors.

Chip Ferrite Bead Replacement Considerations

BLM18HK601SN1D: Lower current rating (100 mA). BLM18SP601SN1D: Higher current rating (1.5 A) but different height (0.6 mm).
