Fixed Inductors Procurement Notes

Verify the manufacturer part number against official API Delevan documentation to ensure authenticity. Confirm that the unshielded configuration aligns with your circuit's electromagnetic compatibility requirements. Check for any specific handling instructions regarding the non-standard package dimensions during assembly.

Fixed Inductors Selection Notes

Select this component when high saturation current and low DC resistance are critical. Ensure the PCB footprint accommodates the 27.44 mm x 12.96 mm non-standard outline. Consider the lack of shielding if proximity to sensitive signal traces exists. Validate thermal management strategies given the 130°C maximum operating limit.

Fixed Inductors Part Context

This part belongs to the 5500R series of high-current power chokes manufactured by Delevan (API Delevan). The series is characterized by large form-factor surface-mount inductors intended for demanding power conversion tasks where standard small-signal inductors cannot handle the required current levels or thermal loads.

Fixed Inductors Replacement Considerations

Cross-reference with other 5500R series variants such as 5500R-472J or 5500R-333J for different inductance values within the same family. Verify pinout and mechanical compatibility before substituting with generic high-current SMD inductors.
