Procurement Notes
Verify the specific suffix designation when ordering, as variations such as 'H' or 'F' may indicate different tolerances or specifications within the same series. Confirm that the required inductance value and current rating align with the 2.2 µH and 257 mA parameters. Ensure the unshielded form factor is compatible with the target PCB layout to prevent interference issues. Cross-reference the manufacturer datasheet for any recent package or material updates before finalizing procurement.
Selection Notes
Select this component for applications requiring a 2.2 µH inductance with moderate current handling capabilities. The unshielded design necessitates careful placement on the PCB to manage magnetic field interactions. Evaluate the self-resonant frequency limit to ensure suitability for the intended signal bandwidth. Consider the axial lead profile for compatibility with existing through-hole assembly processes.
Part Context
This part belongs to the Delevan 0819 series of RF inductors, which are characterized by their molded unshielded construction. The series offers various inductance values and tolerance options to suit different RF requirements. The 0819-32G specifically targets mid-range inductance needs with precise tolerance control.
Replacement Considerations
Direct substitutes within the same series include the 0819-32H, which shares identical electrical parameters but may differ in packaging or minor manufacturing revisions. Verify compatibility with the 0819-32G before substitution.
