- Impedance matching circuits
Procurement Notes
Verify the specific manufacturer part number against official Delevan documentation to confirm exact electrical tolerances and package specifications. Ensure compatibility with surface-mount assembly processes. Confirm RoHS compliance status through the latest datasheet before integration into regulated products.
Selection Notes
Select this component when precise inductance control is required for RF applications. The 1% tolerance distinguishes it from standard general-purpose inductors. Consider the 450 MHz self-resonant frequency limit to ensure operation remains within the intended inductive range for the target circuit frequency.
Part Context
This component belongs to the Delevan 103/R series of fixed RF inductors. The series offers various inductance values and tolerance options tailored for high-frequency electronic designs. The 103R-221FS represents a specific configuration within this family, balancing low DC resistance with high Q-factor performance for sensitive RF environments.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify cross-references only through official manufacturer substitution guides or authorized distributor databases.
