Procurement Notes
Verify the specific manufacturer part number against official datasheets to confirm electrical parameters such as inductance value, tolerance, and current ratings. Ensure compatibility with existing PCB footprints regarding axial lead spacing and overall component dimensions before finalizing procurement decisions.
Selection Notes
Select this component when a low-inductance, high-current RF solution is required. The unshielded design necessitates careful layout consideration to minimize electromagnetic interference with adjacent traces. Verify that the operating frequency remains below the self-resonant frequency to maintain intended inductive behavior.
Part Context
This component belongs to the Delevan 0819 series of fixed RF inductors. The series offers various inductance values and tolerances within a standardized physical footprint. These parts are engineered for general-purpose radio frequency applications requiring reliable performance in compact electronic assemblies.
Replacement Considerations
Cross-reference with other 0819 series variants or equivalent axial RF inductors from different manufacturers. Ensure substitute components match the 220 nH inductance, 3% tolerance, and 645 mA current rating specifications to maintain circuit integrity.
