Fixed Inductors Procurement Notes

Verify the specific suffix =P3 against official Murata documentation to confirm packaging configuration and compliance status. Check for Product Change Notices regarding manufacturing location or material composition updates. Confirm availability status as distribution channels may list obsolete or limited stock indicators that do not reflect direct manufacturer allocation. Ensure the ordering part number matches the exact electrical parameters required for the design.

Fixed Inductors Selection Notes

Select this component when a compact shielded inductor with high saturation current is required for space-constrained power designs. The 1818 footprint offers a balance between thermal performance and board area efficiency. Compare the 2.3 A saturation rating against peak load currents to prevent inductance collapse. Consider the 65 mΩ DCR impact on overall system efficiency and voltage drop during continuous operation.

Fixed Inductors Part Context

This part belongs to the DEM series of power inductors from Murata Electronics. The series is characterized by halogen-free materials and RoHS compliance. These components are engineered for large current applications, providing reliable performance in demanding power conversion environments where magnetic shielding and thermal stability are critical design factors.

Fixed Inductors Replacement Considerations

Consult official Murata documentation for confirmed substitute part numbers. Cross-reference dimensions and electrical parameters carefully. Do not assume interchangeability based solely on inductance values.
