Fixed Inductors Procurement Notes

Verify the specific manufacturer documentation for the PA4546.122NLT to confirm electrical parameters and mechanical tolerances before integration. Ensure that the procurement source provides official datasheets and compliance certificates such as RoHS and REACH status. Cross-reference the part number with the manufacturer's latest release notes to account for any potential lifecycle changes or alternate packaging options available through authorized distributors.

Fixed Inductors Selection Notes

Select this component when a low-profile, high-current inductor is required for automotive or industrial power applications. The 1.2 µH value and 3.5 A rating suit moderate power levels. Compare the 56 mΩ DCR against system loss requirements. Consider the 1.2 mm height limit for strict board clearance constraints. Verify thermal performance under continuous load conditions relative to the specified operating temperature range.

Fixed Inductors Part Context

This part belongs to the PA4546.XXXNLT series of SMT power inductors by Pulse Electronics. The series is characterized by molded powder cores and is qualified to AEC-Q200 standards. Similar parts in the series include PA4546.103NLT and PA4546.183NLT, which offer different inductance values but share the same footprint and height specifications for interchangeable design flexibility.

Fixed Inductors Replacement Considerations

Direct substitutes within the same family include PA4546.103NLT and PA4546.183NLT if inductance adjustments are permissible. For cross-manufacturer replacements, verify that the alternative offers comparable saturation current, DCR, and physical dimensions to ensure board compatibility and electrical performance equivalence.
