Fixed Inductors Procurement Notes

Verify that the specific part number matches the required electrical specifications, particularly the 39 nH inductance and 1 A current rating. Confirm compliance with RoHS directives and REACH regulations before integration. Ensure the 1008 package dimensions align with the PCB footprint requirements. Check for any recent product change notices or end-of-life announcements directly from the manufacturer's official documentation.

Fixed Inductors Selection Notes

Select this component when a low-inductance, high-current SMD inductor is needed for RF filtering or matching networks. The ceramic core offers advantages over ferrite cores in terms of thermal stability. The AEC-Q200 qualification makes it suitable for automotive environments. Consider the unshielded nature for layout sensitivity and the 1.5 GHz self-resonant frequency for bandwidth limitations.
