Procurement Notes
Verify the specific suffix designation against manufacturer documentation to confirm exact electrical tolerances and packaging configuration. Confirm RoHS compliance status as indicated in official datasheets prior to integration. Ensure procurement channels provide valid traceability records for component authenticity and storage history validation.
Selection Notes
Select this component when high inductance values are required within the axial leaded form factor. The 1% tolerance suits precision tuning requirements. Evaluate the 17.5 Ohm DC resistance and 52 mA current limit against circuit load demands. Consider the unshielded design implications for nearby component placement and electromagnetic interference sensitivity.
Part Context
This part belongs to the Delevan 0819 series of molded RF inductors. The series offers various inductance values with different tolerance codes. The 0819-72F represents a higher inductance option compared to lower value variants like the 0819-10H, providing distinct performance characteristics for specific RF band applications.
Replacement Considerations
Cross-reference with other 0819 series parts for alternative inductance values. Verify physical footprint compatibility with existing PCB layouts. Check equivalent specifications from other manufacturers offering axial leaded RF inductors with similar 100 uH ratings.
