Procurement Notes
Verify the specific manufacturer part number against official API Delevan documentation to confirm electrical parameters and physical dimensions. Ensure that the required operating temperature range and current ratings align with the target application design specifications before finalizing procurement decisions.
Selection Notes
Select this component when a high-inductance value is required in a compact axial package. Consider the low maximum DC current rating and relatively high DC resistance when designing power-sensitive circuits. Verify that the unshielded nature does not interfere with nearby sensitive components due to potential magnetic field emission.
Part Context
This component belongs to the Delevan 0819 series of fixed RF inductors. The series offers various inductance values tailored for radio frequency applications. These parts are characterized by their molded construction and axial leads, providing a reliable solution for standard PCB mounting requirements in electronic assemblies.
Replacement Considerations
Consult official API Delevan cross-reference documents for verified substitute part numbers. Do not assume functional equivalence with other manufacturers' components without verifying all electrical and mechanical parameters.
