Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and material specifications. Ensure that the ordering part number matches the required performance parameters for the target application. Cross-reference datasheet revisions to account for any potential manufacturing changes or compliance updates prior to final procurement decisions.
Selection Notes
Select this component when an unshielded RF inductor with 120 nH nominal value is required. Consider the 880 mA current rating and 125 mOhm resistance for power handling needs. Evaluate the 750 MHz self-resonant frequency to ensure suitability for the intended operating bandwidth. Confirm package compatibility with existing PCB footprints and assembly processes.
Part Context
This component belongs to the Delevan 103/R series of RF inductors. The series offers various inductance values optimized for radio frequency circuitry. The 103R-121HS specifically provides a low-inductance solution suitable for higher frequency ranges within the RF spectrum, distinguishing it from power or common mode variants in the broader product catalog.
Replacement Considerations
Consult official substitution lists for verified equivalent part numbers. Generic cross-references may not guarantee identical RF performance or physical dimensions.
