Fixed Inductors Procurement Notes

Verify the specific part number against official Pulse Electronics documentation to confirm electrical parameters and packaging details. Ensure compatibility with AEC-Q200 requirements if used in automotive applications. Check RoHS3 compliance status prior to procurement. Confirm lead times and availability through authorized distributors as inventory levels fluctuate.

Fixed Inductors Selection Notes

Select this component when a low-profile, unshielded inductor is required for space-constrained designs. The 1.20 mm height suits applications with strict vertical clearance limits. Consider the 97 mΩ DCR for efficiency calculations in low-current scenarios. Verify that the 2.3 A continuous current rating meets the circuit's operational demands without excessive heating.

Fixed Inductors Part Context

This part belongs to the PM4546 series of high-current, molded SMT power inductors. The series offers various inductance values tailored for different current requirements while maintaining a consistent footprint. The PM4546.332NLT specifically provides 3.3 µH inductance, balancing size and performance for moderate current applications.

Fixed Inductors Replacement Considerations

Cross-reference with other PM4546 series variants for different inductance or current ratings. Ensure substitute parts match the 4.45 x 4.06 x 1.20 mm dimensions and AEC-Q200 qualification if automotive use is intended.
