Procurement Notes

Verify the specific datasheet version for the 0819-52G to confirm RoHS compliance status and exact electrical tolerances prior to procurement. Ensure that the maximum DC current rating of 118 mA aligns with the thermal requirements of the target application environment. Confirm packaging quantities match production needs as factory pack quantities may vary by distributor.

Selection Notes

Select the 0819-52G when a precise 15 uH inductance with low tolerance is required for RF signal paths. The unshielded design necessitates careful layout consideration to minimize electromagnetic interference with adjacent components. Compare the 3.4 ohm DC resistance against power loss constraints in the circuit design.

Part Context

This component belongs to the Delevan 0819 series of fixed RF inductors. These parts are characterized by their molded epoxy construction and axial leads, distinguishing them from surface-mount alternatives. The series offers various inductance values tailored for radio frequency applications requiring stable performance.

Replacement Considerations

Direct substitutes within the same series include the 0819-54G (18 uH) or 0819-48F (10 uH) if inductance adjustments are permissible. Verify that replacement parts maintain compatible axial dimensions and current ratings.
