Chip Ferrite Bead Procurement Notes

Verify the specific suffix against official Murata documentation to confirm packaging type and performance characteristics. Ensure the selected variant matches the required impedance tolerance and current rating for the target application circuit design.

Chip Ferrite Bead Selection Notes

Select this component when a compact 0402 form factor is required for EMI suppression. Consider the 200 mA current limit and 800 mΩ DC resistance to ensure compatibility with the power budget and signal integrity requirements of the specific circuit node.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM15 series of chip ferrite beads. The series offers various impedance values and current ratings within the standard 0402 package size, providing designers with options for different noise filtering needs while maintaining a small physical footprint.

Chip Ferrite Bead Replacement Considerations

BLM15BX221SN1D offers similar electrical characteristics but supports a higher rated current of 450 mA. Verify if the increased current capacity aligns with the application requirements before substitution.
