Fixed Inductors Procurement Notes

Verify the specific suffix codes on the ordering part number to ensure correct tolerance and packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when ultra-compact dimensions are required alongside precise low-nanohenry inductance values. Ensure the operating frequency remains below the 8.5 GHz self-resonant point to maintain inductive behavior. Validate that the 270 mA current rating meets the circuit's peak load requirements.

Fixed Inductors Part Context

This component belongs to the Murata LQP series of thin-film RF inductors. The series is engineered for mobile and wireless applications requiring small form factors and high reliability. The LQP02TQ variant specifically utilizes thin-film processes to achieve consistent electrical characteristics across varying environmental conditions.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 4.7 nH value, 01005 package, and similar current ratings. Consult official Murata documentation for cross-reference lists or updated series replacements.
