Fixed Inductors Procurement Notes

Verify the specific package dimensions and termination style against the official datasheet to ensure compatibility with your PCB layout. Confirm that the 450 mA current rating meets your circuit's peak and continuous load requirements. Check for any RoHS compliance documentation if required by your manufacturing standards.

Fixed Inductors Selection Notes

Select this component when a low-inductance, high-frequency solution is required. The unshielded design may necessitate careful placement to avoid coupling with nearby traces. Ensure the operating environment stays within the specified thermal limits and that the 360 mOhms resistance does not cause excessive voltage drop or power loss in the application.
