Procurement Notes
Verify the manufacturer part number against official Delevan documentation to ensure accuracy. Confirm that the specific suffix indicates the correct tolerance and packaging configuration. Check for RoHS compliance status as indicated in the datasheet. Ensure the ordering quantity aligns with the reel packaging requirements specified by the manufacturer.
Selection Notes
Select this component when a 56 uH inductance value is required for RF circuits. Consider the 69 mA current limit and 10 Ohm DC resistance for power handling constraints. The unshielded design requires careful layout consideration to minimize electromagnetic interference with adjacent components. Verify the axial package dimensions fit the target PCB footprint.
Part Context
This component belongs to the Delevan 0819 series of RF inductors. The series offers various inductance values with different tolerances and current ratings. The 0819-66J specifically targets applications requiring moderate inductance with high Q performance in the lower RF spectrum.
Replacement Considerations
Consult official Delevan substitution guides for verified equivalents. Cross-reference specifications such as inductance, tolerance, current rating, and physical dimensions before substituting.
