Fixed Inductors Procurement Notes

Verify the specific ordering suffix against official Wurth Elektronik documentation to ensure correct electrical parameters and packaging configuration. Confirm that the requested quantity matches the standard reel or cut-tape availability. Check for any recent product change notifications regarding marking or material composition updates prior to finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a compact, shielded inductor with moderate current handling is required. The 1 µH value suits many switching regulator topologies. Ensure the PCB footprint accommodates the 3030 metric package size. Consider the saturation current limit relative to peak circuit loads to prevent performance degradation during transient events.

Fixed Inductors Part Context

This part belongs to the WE-MAPI family of shielded power inductors from Würth Elektronik. The series is characterized by its low profile and high current density capabilities. It is distinct from wire-wound types due to its molded construction, offering improved reliability in harsh environments compared to open-core alternatives.

Fixed Inductors Replacement Considerations

Direct substitutes include other 1 µH, 3030 package shielded inductors from Würth such as the 74438334010 variants with different current ratings. Cross-brand replacements require matching inductance, DCR, Isat, and physical dimensions. Verify AEC-Q200 status if automotive application is critical.
