Procurement Notes
Verify RoHS compliance status prior to procurement, as documentation indicates potential non-compliance or lead content variations within the 0819 series. Confirm specific manufacturing date codes and supply chain authenticity through authorized distributors. Ensure that the selected variant matches the required tolerance and current ratings for the target application environment.
Selection Notes
Select this component when a 3.3 µH inductance value is required for RF circuits with moderate current handling needs up to 198 mA. Consider the unshielded nature of the design for layout planning to minimize electromagnetic interference coupling. Verify that the axial package dimensions fit the available PCB real estate and that the self-resonant frequency aligns with the operational bandwidth requirements.
Part Context
The 0819-36K belongs to the Delevan 0819 series of fixed RF inductors. This series is characterized by molded, unshielded coils designed for high-frequency performance. The part represents a standard axial leaded option within the lineup, providing a balance between electrical performance and mechanical robustness for general RF applications.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source data. Cross-reference with other 3.3 µH axial RF inductors only after verifying electrical parameter equivalence and mechanical footprint compatibility.
