Fixed Inductors Procurement Notes

Verify the specific ordering suffix and manufacturing date code upon procurement, as component availability may vary by region. Confirm compliance with relevant environmental directives such as RoHS status before integration into final assemblies. Ensure storage conditions adhere to moisture sensitivity level requirements to maintain solderability and electrical integrity during the manufacturing process.

Fixed Inductors Selection Notes

Select this component when an unshielded inductor is required to minimize electromagnetic interference coupling in adjacent circuit traces. The 1.4 µH value and 2.5 A current rating suit moderate power density designs. Consider the 125°C operating limit for high-thermal environments where standard 100°C rated parts may be insufficient. Verify footprint compatibility with the target PCB layout constraints.
