Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with RoHS requirements if mandated by the target application environment. Cross-reference datasheet parameters such as DC resistance and current ratings against system constraints before finalizing procurement decisions.
Selection Notes
Select this component when precise 22 µH inductance is required in an axial form factor. Consider the 105 mA current rating and 4.3 Ohm DCR limits during thermal and power budget analysis. The unshielded nature requires careful layout planning to minimize electromagnetic interference with adjacent sensitive traces or components in dense RF assemblies.
Part Context
This part belongs to the Delevan 0819 series of fixed RF inductors. These components are characterized by their molded, unshielded construction and axial leads. The series offers various inductance values tailored for radio frequency signal processing and impedance matching tasks in electronic equipment requiring reliable passive magnetic components.
Replacement Considerations
Consult official substitution guides for equivalent parts. Verify that any alternative maintains identical inductance, tolerance, current rating, and physical dimensions to ensure mechanical and electrical compatibility without redesigning the printed circuit board.
