Procurement Notes
Verify the specific manufacturer part number against official Delevan documentation to confirm electrical parameters such as inductance value, tolerance, and current ratings. Ensure the component meets required RoHS compliance standards and operating temperature ranges before procurement. Cross-reference datasheets to validate package dimensions and termination styles for accurate PCB footprint compatibility.
Selection Notes
Select this component based on its 22 nH inductance and 1.8 GHz self-resonant frequency for high-frequency signal handling. Consider the 950 mA current rating and 108 mΩ DC resistance for power efficiency requirements. The unshielded design requires careful layout consideration to prevent magnetic coupling with nearby components in dense RF assemblies.
Part Context
This component belongs to the 103/R series of fixed inductors manufactured by API Delevan. The series offers various inductance values tailored for radio frequency applications. The 103R-220MS specifically provides a low-inductance solution within this lineup, designed for compact electronic systems requiring precise impedance matching or filtering characteristics at high frequencies.
Replacement Considerations
Consult official Delevan documentation for verified substitute part numbers within the same series or equivalent specifications from other manufacturers.
