Procurement Notes
Verify RoHS status carefully as sources indicate lead content. Confirm package type matches design requirements. Check datasheet for specific thermal limits and current derating curves. Ensure supplier provides original manufacturer documentation to validate component authenticity and specifications before integration into production.
Selection Notes
Select this part for applications requiring 1.8 µH inductance with moderate current handling. Compare Q factor and self-resonant frequency against circuit requirements. Consider physical size constraints relative to the 5.08 mm length. Evaluate alternative tolerances if tighter precision is needed.
Part Context
Part of the Delevan 0819 series of fixed RF inductors. Shares common physical dimensions and mounting style with other variants in the series. Designed for high-frequency applications where unshielded performance is acceptable.
Replacement Considerations
Cross-reference with other 0819 series variants such as 0819-30F or 0819-30H for different tolerance options. Verify equivalent inductance and current ratings when substituting.
