Fixed Inductors Procurement Notes

Verify the specific suffix and manufacturer documentation when sourcing. Confirm that the component meets required thermal and current specifications for the target application. Ensure compatibility with standard surface-mount reflow processes. Check for any updated replacement part numbers or series designations provided by the manufacturer prior to finalizing procurement plans.

Fixed Inductors Selection Notes

Select this component for applications requiring compact power filtering with moderate current handling capabilities. The semi-shielded design helps minimize magnetic field interference with nearby components. Evaluate the 460 mA current rating against peak load requirements. Consider the 1.001 Ohm DC resistance impact on overall circuit efficiency and voltage drop during operation.

Fixed Inductors Part Context

This part belongs to the LSQPA series of fixed inductors from Taiyo Yuden. It serves as a successor or variant within the broader CB/LSQ family of power inductors designed for consumer electronics.
