103R-472GS

Overview

The Delevan 103R-472GS is an unshielded surface-mount RF inductor with a nominal inductance of 4.7 µH and a tolerance of ±2%. It features a maximum DC resistance of 1.8 Ohms and supports a maximum DC current of 230 mA. The component operates within a temperature range of -55°C to +125°C, exhibits a minimum Q factor of 30, and has a self-resonant frequency of 40 MHz. Its physical dimensions are 2.92 mm in length, 2.66 mm in width, and 2.41 mm in height.

Feature Summary

• Unshielded construction for minimal magnetic interference
• High stability across extended temperature ranges
• Standard SMD/SMT termination for PCB mounting

Applications

• RF circuit filtering
• Impedance matching networks
• General-purpose RF 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 pick-and-place equipment regarding the nonstandard lead configuration. Cross-reference datasheet revisions to validate thermal performance limits before final integration.

Selection Notes

Select this component when a 4.7 µH inductance value is required with tight ±2% tolerance. Consider the 230 mA current rating for power handling constraints. The unshielded design necessitates careful layout planning to prevent coupling with adjacent components in dense RF assemblies.
