BLM18BD252SH1D

Chip Ferrite Bead Overview

The Murata BLM18BD252SH1D is a single-line ferrite chip bead in a 0603 (1608 metric) surface-mount package. It provides an impedance of 2500 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 150 mA and has a maximum DC resistance of 1.5 Ohms. It operates within a temperature range of -55°C to +125°C and meets AEC-Q200 automotive qualification standards.

Chip Ferrite Bead Feature Summary

• Designed for high-speed signal line noise suppression
• Automotive-grade reliability via AEC-Q200 certification
• Compact 0603 footprint for space-constrained layouts

Chip Ferrite Bead Applications

• High-speed digital signal lines
• Automotive electronic systems
• Noise suppression in sensitive circuitry

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SH1D against official Murata documentation to confirm package dimensions and termination style. Ensure the selected variant matches the required impedance tolerance and current rating for the target application. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm authenticity and availability status before ordering.

Chip Ferrite Bead Selection Notes

Select this component when high attenuation is required on high-speed signals within automotive or industrial environments. The 0603 size balances board space efficiency with sufficient current handling for low-power signal lines. Verify that the 150 mA current limit aligns with the operational requirements of the protected circuit to prevent saturation or excessive heating during normal operation.

Chip Ferrite Bead Part Context

This part belongs to the BLM18 series of ferrite beads, which are widely used for EMI suppression in compact electronics. The BD designation typically indicates specific impedance characteristics optimized for high-frequency noise damping. As a single-line component, it is intended for use on individual signal traces rather than power distribution networks.

Chip Ferrite Bead Replacement Considerations

Check Murata's official substitution guide for equivalent parts within the BLM18 family. Ensure any alternative maintains the same 0603 footprint, 2500 Ohm impedance at 100 MHz, and AEC-Q200 qualification if automotive compliance is mandatory.
