It features a maximum DC resistance of 230 mΩ and supports a maximum DC current of 650 mA. The component has a self-resonant frequency of 375 MHz and a minimum Q factor of 49 at 25 MHz. Physical dimensions are 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height.

Feature Summary

• Unshielded construction for minimal magnetic interference
• Surface-mount design for automated PCB assembly
• High self-resonant frequency for RF applications

Applications

• RF circuit filtering
• Impedance matching networks
• General purpose RF inductors

Procurement Notes

Verify the specific suffix 'GS' against the manufacturer's official datasheet to confirm exact tolerance and current ratings. Ensure the ordering quantity aligns with the standard reel packaging requirements specified by Delevan. Cross-reference the Mouser part number 807-103R-271GS for accurate availability status.

Selection Notes

Select this component when a low-inductance value near 270 nH is required for high-frequency operation. The unshielded design necessitates careful layout planning to prevent crosstalk. Verify that the 650 mA current rating meets the circuit's peak load requirements and that the 230 mΩ DCR fits within power loss constraints.

Part Context

This part belongs to the 103/R series of fixed RF inductors manufactured by API Delevan. The series offers various inductance values optimized for radio frequency applications. The 103R-271GS specifically targets circuits requiring precise 2% tolerance inductance at frequencies up to its self-resonant point.

Replacement Considerations

Public confirmed substitute part numbers: 103R-271KS (10% tolerance), 103R-271HS (1% tolerance). Verify compatibility regarding tolerance differences and current ratings before substitution.
