Fixed Inductors Procurement Notes

Verify the specific package type (SMD vs. through-hole) as data sources indicate conflicting physical dimensions. Confirm the manufacturer part number against official Traco Power documentation to ensure accuracy, as third-party listings may contain inconsistent specifications regarding size and mounting style.

Fixed Inductors Selection Notes

Select this component for applications requiring a 33 µH inductance with a 1.2 A current handling capacity. Ensure the chosen package variant matches the PCB layout constraints, noting discrepancies between reported SMD and larger footprint dimensions in available public records.

Fixed Inductors Part Context

Traco Power produces passive components alongside its DC/DC converters. The TCK series includes various inductors and chokes. This specific model serves as a basic passive element for circuit stabilization and filtering within broader power management systems designed by the manufacturer.

Fixed Inductors Replacement Considerations

No officially confirmed substitute part numbers are documented in the provided source material. Cross-reference electrical parameters such as inductance, current rating, and resistance when evaluating generic alternatives.
