Fixed Inductors Procurement Notes

Verify the specific package dimensions against your PCB footprint, as the datasheet classifies the case as non-standard. Confirm that the 570 mA current rating meets your circuit's peak load requirements. Ensure compatibility with standard reflow soldering profiles for lead-free assemblies. Check for RoHS compliance status prior to final procurement approval.

Fixed Inductors Selection Notes

Select this component when a high inductance value is required in a compact surface-mount form factor. The unshielded nature may necessitate careful layout planning to minimize electromagnetic interference coupling with nearby traces. Consider the higher DC resistance impact on efficiency if low-loss performance is critical for the application.
