BLM18KG101JH1D

Chip Ferrite Bead Overview

The BLM18KG101JH1D is a single-line ferrite bead from the EMIFIL BLM18KG series, manufactured by Murata Electronics. It features a 0603 (1608 metric) surface-mount package with dimensions of 1.6 mm length and 0.8 mm width. The component provides an impedance of 100 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current rating of 1.9 A and exhibits a maximum DC resistance of 30 mOhms. The device operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification for automotive reliability.

Chip Ferrite Bead Feature Summary

• High current handling capability up to 1.9 A in a compact 0603 footprint
• Low DC resistance of 30 mOhms to minimize power loss
• AEC-Q200 qualified for automotive electronic applications
• Wide operating temperature range suitable for harsh environments

Chip Ferrite Bead Applications

• DC power line filtering for portable mobile equipment
• Noise suppression in cellular phone power circuits
• Filtering for notebook PC and PDA power supplies
• Audio system power line noise reduction

Chip Ferrite Bead Procurement Notes

Verify the specific suffix JH1D against official Murata documentation to confirm tape and reel packaging specifications. Ensure the ordered part matches the AEC-Q200 automotive grade requirement if used in vehicle electronics. Cross-reference the impedance value at 100 MHz with circuit simulation tools like SimSurfing to validate performance under actual load conditions before finalizing procurement.

Chip Ferrite Bead Selection Notes

Select this component when space constraints require a 0603 package but high current capacity is necessary. The low DC resistance makes it suitable for battery-powered devices where efficiency is critical. Compare its 1.9 A rating against alternative 0805 or 1206 beads to balance board area savings with current handling needs. Ensure the 100 Ohm impedance aligns with the target noise frequency spectrum of the application.

Chip Ferrite Bead Part Context

This part belongs to the BLM18KG series, designed as a high-current power chip ferrite bead. It offers improved current management compared to conventional 0603 ferrite beads, handling up to twice the rated current while maintaining low DC resistance. The series aims to replace larger size beads, providing cost-effective noise suppression for compact consumer and automotive electronics.
