Chip Ferrite Bead Procurement Notes

Verify the specific suffix WH1D against official Murata documentation to confirm the glue-only construction and exact physical dimensions. Ensure the selected variant matches the required 1.5A current rating and 55mOhm DC resistance specifications for the target application circuit design.

Chip Ferrite Bead Selection Notes

Select this component when a 0603 footprint is required for power line filtering with a 100 Ohm impedance target. Consider the 1.5A current handling capability and low DC resistance for efficiency. Verify compatibility with automated assembly processes due to the specific package height and termination type.

Chip Ferrite Bead Part Context

This part belongs to the Murata EMIFIL BLM18KG series, which offers various impedance values and current ratings within the 0603 form factor. The KG series typically includes automotive-qualified options, distinguishing it from general-purpose ferrite beads by adhering to stricter reliability standards for harsh environments.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other BLM18KG series parts with identical 100 Ohm impedance and compatible current ratings, such as BLM18KG101SN1D or BLM18KG101TN1D, provided their specific electrical parameters like DC resistance and current limits meet the design requirements.
