Chip Ferrite Bead Procurement Notes

Verify the specific suffix WH1D against official Murata documentation to confirm the exact impedance, current rating, and termination specifications. Confirm availability status as distribution sources may list this part as obsolete or end-of-life. Ensure the procurement channel provides valid traceability and authenticity guarantees for automotive-grade components.

Chip Ferrite Bead Selection Notes

Select this component when a 0603 footprint is required for high-current applications needing 330 Ohms attenuation at 100 MHz. The AEC-Q200 qualification makes it suitable for automotive environments requiring extended temperature stability up to 150°C. Compare the 110 mOhms DCR against system voltage drop requirements to ensure compatibility with the 1.25 A rated current.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM18KG series of ferrite beads designed for compact electronics. The series utilizes specialized materials to provide effective electromagnetic interference suppression while maintaining low DC resistance.
