Applications
- RF circuit filtering
- Impedance matching networks
- General purpose RF signal processing
Procurement Notes
Verify the specific manufacturer designation, as API DELEVAN and Delevan are associated with this part number. Confirm RoHS compliance status through official documentation before integration. Ensure the unshielded characteristic aligns with your electromagnetic interference requirements. Validate that the 610 mA current rating meets your circuit's operational demands.
Selection Notes
Select this component when an unshielded RF inductor is required to minimize cost or size constraints. The 470 nH value suits high-frequency applications where self-resonance near 215 MHz is acceptable. Consider the 260 mOhm resistance for power loss calculations. Compare against shielded alternatives if magnetic field containment is necessary for adjacent components.
Part Context
This part belongs to the 103/R series of fixed inductors manufactured by API DELEVAN. It is categorized under RF Inductors - SMD. The series provides general-purpose inductive solutions for surface-mount technology. The 103R-471JS specifically targets radio frequency environments requiring precise inductance values.
Replacement Considerations
The 103R-471HS is a documented equivalent with similar electrical characteristics but a tighter 3% tolerance. Verify compatibility regarding the tolerance difference and ensure the unshielded nature of both parts matches your design specifications.
