BLM18BD601SZ1D

Chip Ferrite Bead Overview

The Murata BLM18BD601SZ1D is a single-line chip ferrite bead in the BLM18BD series, housed in a 0603 (1608 metric) surface-mount package measuring 1.6 mm x 0.8 mm x 0.8 mm. It provides an impedance of 600 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 200 mA and features a maximum DC resistance of 650 mOhms. It operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Designed to function as a resistor at noise frequencies to minimize resonance risks
• Single-line configuration for signal line applications
• Unshielded construction suitable for general EMI suppression

Chip Ferrite Bead Applications

• High-speed signal line noise suppression
• General electronic circuit EMI filtering

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'SZ1D' against official Murata documentation to confirm packaging details and availability status. Ensure the selected variant matches the required impedance and current ratings for the target application. Cross-reference datasheets for any recent manufacturing changes or obsolescence notices before finalizing procurement plans.

Chip Ferrite Bead Selection Notes

Select this component when a 0603 footprint is required for high-impedance noise suppression on sensitive signal lines. The 200 mA rating limits suitability for power rails; it is optimized for low-current digital or analog signals. Verify that the 650 mOhm DCR does not introduce excessive voltage drop in the specific circuit design.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM18BD series, which focuses on high-impedance performance for noise reduction. It shares the standard 0603 mechanical dimensions with other BLM18 variants but differs in magnetic material properties and current handling capabilities compared to lower-impedance models like the BLM18PG series.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include BLM18BD601SN1J, which offers identical electrical specifications but may differ in reel packaging quantity. Other BLM18BD variants with matching 600 Ohm impedance can be considered if pin compatibility and thermal ratings are verified.
