Fixed Inductors Procurement Notes

Verify the specific suffix against official Wurth documentation to confirm exact electrical tolerances and packaging configuration. Ensure the procurement channel provides valid traceability documents required for automotive-grade components. Cross-reference the manufacturer part number with distributor catalogs to confirm current production status and lead times before finalizing orders.

Fixed Inductors Selection Notes

Select this component when an unshielded inductor is acceptable to minimize cost and height while maintaining high current handling. The 82 µH value suits intermediate frequency switching applications. Verify that the PCB footprint matches the non-standard package dimensions provided in the datasheet. Consider thermal management requirements given the 250 mΩ resistance at rated current.

Fixed Inductors Part Context

This part belongs to the WE-PD2A family of shielded and unshielded power inductors. The series is characterized by high current density and robust construction suitable for harsh environments. The 784776182 specifically utilizes an unshielded variant, offering different electromagnetic interference characteristics compared to its shielded counterparts within the same product line.

Fixed Inductors Replacement Considerations

Direct substitutes include other 82 µH unshielded SMD inductors with comparable Irms and Isat ratings from Würth or alternative manufacturers. Ensure any replacement maintains AEC-Q200 compliance if used in automotive contexts. Verify mechanical footprint compatibility and thermal performance metrics before substitution.
