Procurement Notes
Verify the specific manufacturer designation, as sources list both API Delevan and Delevan. Confirm RoHS compliance status, as documentation varies between detailed compliance and non-compliant designations. Ensure the ordering suffix matches the required tolerance and packaging format. Cross-reference datasheet parameters against schematic requirements to confirm suitability for the target frequency range and current load.
Selection Notes
Select this component for low-inductance RF filtering or matching networks requiring high current handling up to 525 mA. The unshielded design necessitates careful layout consideration to prevent magnetic coupling with adjacent components. Verify that the 440 MHz self-resonant frequency aligns with the operational bandwidth. Compare physical dimensions against available PCB footprint constraints before finalizing the design.
Part Context
This part belongs to the 0819 series of RF inductors manufactured by Delevan. The series includes various variants with different inductance values, tolerances, and current ratings. The 0819-10G represents a specific configuration within this family, characterized by its 270 nH value and 3% tolerance. It shares common physical dimensions and mounting styles with other members of the series.
Replacement Considerations
Direct substitutes within the same series include the 0819-10H, which offers identical electrical characteristics but with a 3% tolerance compared to the standard specification. Other variants in the 0819 series may serve as alternatives if parameter adjustments are acceptable. Verify pin compatibility and thermal performance when considering cross-series replacements.
