Procurement Notes
Verify the manufacturer designation as API Delevan or Delevan during sourcing. Confirm the specific suffix JS indicates the required tolerance level. Check datasheets for RoHS compliance status prior to integration. Ensure the supplier provides valid traceability documentation for quality assurance purposes.
Selection Notes
Select this component when a 39 µH inductance with tight tolerance is required in a small footprint. Evaluate the 38 mA current limit against peak circuit demands. Compare the 17 Ohm DC resistance impact on signal loss. Consider the shielded type for noise-sensitive environments compared to unshielded alternatives.
Part Context
This component is part of the 108R series of shielded surface-mount inductors manufactured by API Delevan. The series offers various inductance values within a standardized 2.5x2.5 mm package. These parts are designed for high-frequency applications where size constraints and magnetic shielding are critical design factors.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with alternative manufacturers based on identical electrical parameters and mechanical dimensions before substitution.
