Fixed Inductors Procurement Notes

Verify the specific suffix HZ to confirm the automotive-grade variant and AEC-Q200 qualification status. Check the official manufacturer documentation for the most recent production status, as this part may be subject to discontinuation notices or lifecycle changes. Ensure compatibility with standard reflow soldering profiles for surface mount assembly.

Fixed Inductors Selection Notes

Select this component when a compact 10x10mm footprint is required alongside high current handling capabilities. The 1.0 µH value suits intermediate frequency switching applications. Compare the 8.5 A saturation limit against peak load requirements to prevent inductance collapse. Consider the low DCR for minimizing conduction losses in efficiency-critical designs.
