Overview
The Delevan 103R-471GS is an unshielded surface-mount RF inductor with a nominal inductance of 470 nH and a tolerance of ±2%. It features a maximum DC resistance of 260 mΩ and supports a maximum DC current of 610 mA. The component has a minimum Q factor of 22 and a self-resonant frequency of 215 MHz. Its physical dimensions are 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height. The device utilizes standard SMD/SMT termination and belongs to the 103/R series.
Feature Summary
- Unshielded construction for specific RF circuit requirements
- High self-resonant frequency capability for RF applications
- Standard SMD/SMT termination for PCB mounting
Applications
- RF circuits
- Embedded applications
Procurement Notes
Verify the exact suffix designation against official API Delevan documentation, as variations such as 'K' or 'J' indicate different tolerances. Confirm RoHS compliance status directly from the manufacturer's datasheet before procurement. Ensure the ordering quantity aligns with the specified reel packaging requirements provided by the supplier.
Selection Notes
Select this component when a 470 nH inductance value with tight ±2% tolerance is required for RF designs. Consider the 610 mA current rating and 260 mΩ DCR limits for power handling needs. The unshielded design may influence layout decisions regarding magnetic interference compared to shielded alternatives like the S4924R series.
Part Context
This part belongs to the Delevan 103/R series of fixed inductors. It shares similar electrical characteristics with variants like the 103R-471K (±10% tolerance) and 103R-471J (±5% tolerance), differing primarily in precision. The 103R-471GS represents a higher precision option within this specific unshielded form factor.
Replacement Considerations
The 103R-471K and 103R-471J are direct mechanical substitutes with identical dimensions but looser tolerances. For shielded alternatives, the S4924R-471K offers similar inductance but different current ratings and dimensions.
