Procurement Notes
Verify the specific suffix 'G' against official manufacturer documentation to confirm compliance details and availability status. Cross-reference the Mouser part number 807-103R-471G or DigiKey listing for accurate sourcing channels. Ensure the component meets RoHS requirements as specified in the datasheet before integration into production workflows.
Selection Notes
Select this component when a precise 470 nH inductance is required with tight ±2% tolerance. The unshielded design suits applications where magnetic isolation is not critical. Verify that the 610 mA current rating and 215 MHz self-resonant frequency align with the target circuit's operational parameters and thermal constraints.
Part Context
This part belongs to the 103/R series of fixed RF inductors manufactured by Delevan. It is designed for surface-mount technology (SMT) PCB assembly. The series offers various inductance values optimized for radio frequency applications, providing reliable performance in compact electronic designs requiring stable inductive characteristics.
Replacement Considerations
The 103R-471J serves as a direct substitute with identical electrical specifications but a wider ±5% tolerance. For higher precision needs, the 4302-471G offers similar inductance with tighter tolerances but different physical dimensions. Always verify pin compatibility and thermal ratings before substitution.
