103R-103GS

Overview

The Delevan 103R-103GS is an unshielded surface-mount RF inductor with a nominal inductance of 10 uH and a tolerance of 2%. It features a maximum DC resistance of 3.45 ohms and supports a maximum DC current of 130 mA. The component exhibits a minimum Q factor of 25 and a self-resonant frequency of 28 MHz. Its physical dimensions are 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height.

Feature Summary

• Unshielded construction for standard RF applications
• High precision 2% inductance tolerance
• Compact SMD form factor suitable for space-constrained PCBs

Applications

• RF circuit filtering
• Impedance matching networks
• General radio frequency signal processing

Procurement Notes

Verify the specific suffix 'GS' against official manufacturer documentation to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with standard reflow soldering profiles for SMD components. Cross-reference the 3.45 ohm DCR value with the latest datasheet to prevent integration errors in high-current sensitive designs.

Selection Notes

Select this component when a precise 10 uH inductance with tight 2% tolerance is required for RF stages. The unshielded design may necessitate careful layout planning to minimize electromagnetic interference with adjacent traces. Evaluate the 130 mA current rating against peak load requirements to ensure reliable operation without saturation.

Part Context

This part belongs to the Delevan 103/R series of RF inductors. It shares the same 1005 metric footprint (2.54 x 2.54 mm) as other variants in the family, such as the 103R-102HS and 103R-183KS. The series offers various inductance values and tolerance options within a consistent physical envelope.

Replacement Considerations

Direct substitutes include the 103R-103G if the GS suffix denotes a specific packaging variant rather than a functional change. Verify that alternative parts maintain the 10 uH nominal value, 2% tolerance, and comparable self-resonant frequency characteristics.
