103R-221GS

Overview

The Delevan 103R-221GS is an unshielded surface-mount RF inductor with a nominal inductance of 220 nH and a tolerance of ±2%. It features a maximum DC resistance of 220 mΩ and supports a maximum DC current of 665 mA. The component has a minimum Q factor of 40 and a self-resonant frequency of 430 MHz. Its physical dimensions are 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height.

Feature Summary

• Unshielded chip construction for standard RF applications
• High-Q performance suitable for resonant circuits
• Compact SMD footprint for space-constrained PCBs

Applications

• RF matching networks
• Filter circuits
• Oscillator tanks

Procurement Notes

Verify the specific suffix 'GS' against official manufacturer documentation to confirm exact tolerance and packaging specifications. Ensure compatibility with RoHS requirements if mandated by the end application. Cross-reference the Mouser part number 807-103R-221GS for accurate distributor data sheets and availability status.

Selection Notes

Select this component when a low-inductance, high-frequency solution is required. The 220 nH value and 430 MHz self-resonant frequency make it appropriate for VHF band operations. Consider the unshielded design implications regarding electromagnetic interference coupling in dense layouts compared to shielded alternatives.

Part Context
