Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and packaging configurations. Ensure that the ordering information aligns precisely with the required inductance value and current ratings for the target application design specifications.
Selection Notes
Select this component when an unshielded RF inductor with 1 µH nominal inductance is required. Consider the 425 mA current limit and 540 mΩ resistance for power handling constraints. Verify compatibility with the intended operating frequency range relative to the 145 MHz self-resonant frequency specification.
Part Context
This part belongs to the 103/R series of fixed inductors manufactured by Delevan. The series provides various inductance values tailored for RF applications. The 103R-102G represents a specific configuration within this family, characterized by its 1 µH rating and unshielded chip style suitable for high-frequency circuit implementations.
Replacement Considerations
Consult official manufacturer cross-reference lists for verified substitute part numbers. Do not assume functional equivalence based on generic parameter matching without verifying specific electrical characteristics and physical footprint compatibility.
