Fixed Inductors Procurement Notes

Verify the specific suffix 'B8' against official Murata documentation to confirm the exact tolerance and current rating specifications. Ensure compatibility with standard SMT reflow processes. Confirm RoHS compliance status as per the latest datasheet revision. Check for alternative packaging options such as cut tape or reel if volume requirements differ from standard factory quantities.

Fixed Inductors Selection Notes

Select this component for applications requiring low inductance values with high current capacity. The unshielded type is ideal where magnetic interference is not a concern. Consider the 10 GHz self-resonant frequency for high-frequency operation. Compare with shielded variants if electromagnetic interference suppression is required. Verify PCB footprint dimensions match the 0402 metric package.

Fixed Inductors Part Context

This part belongs to the Murata LQW15AN series of chip RF inductors. These components are designed for use in RF circuits, offering stable performance across wide temperature ranges.
