BLM18BD152SH1D

Chip Ferrite Bead Overview

The Murata BLM18BD152SH1D is a single-line ferrite chip bead in a 0603 (1608 metric) surface-mount package. It provides an impedance of 1.5 kOhms at 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 150 mA and has a maximum DC resistance of 1.2 Ohms. It operates within a temperature range of -55°C to +125°C, with physical dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height.

Chip Ferrite Bead Feature Summary

• Provides high impedance for effective electromagnetic interference suppression in compact designs
• Single-line configuration suitable for differential mode noise filtering applications
• Designed for surface-mount assembly on printed circuit boards

Chip Ferrite Bead Applications

• High-speed signal line noise suppression
• EMI suppression filters in portable devices
• Noise reduction in digital circuits

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'H1D' against official Murata documentation to confirm packaging details and tape-and-reel specifications. Ensure compatibility with standard 0603 footprints during layout. Cross-reference impedance values at 100 MHz with system requirements. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement.

Chip Ferrite Bead Selection Notes

Select this component when a 0603 footprint is required for EMI filtering with a 1.5 kOhm impedance target. The 150 mA current rating limits suitability for power lines; it is intended for signal integrity management. Compare against the BLM18HE series if higher current handling is necessary, as that variant supports 500 mA. Verify thermal performance within the specified -55°C to +125°C operating range.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM18BD series of ferrite beads, designed for general-purpose noise suppression. It shares the 0603 form factor with other variants but differs in impedance and current ratings. The BD series typically targets applications requiring moderate current capacity with significant high-frequency attenuation.

Chip Ferrite Bead Replacement Considerations

The BLM18BD152SN1D offers identical electrical characteristics including 1.5 kOhm impedance and 150 mA rating. Verify if the suffix change indicates a difference in packaging or reel quantity rather than functional alteration.
