• High precision 1% inductance tolerance
• Standard SMD/SMT termination style

Applications

• RF circuit filtering
• Impedance matching networks
• General purpose RF signal processing

Procurement Notes

Verify the specific suffix 'FS' against official manufacturer documentation to confirm exact tolerances and packaging specifications. Ensure compatibility with standard reflow soldering profiles for SMD components. Confirm RoHS compliance status through the latest datasheet revision before final procurement decisions.

Selection Notes

Select this component when high precision inductance is required for RF circuits. The 1010 package size offers a balance between power handling and board space constraints. Consider the 195 mA current rating and 2.5 Ohm resistance for thermal management in the target application environment.

Part Context

This part belongs to the 103/R series of fixed RF inductors manufactured by Delevan. The series provides various inductance values and tolerance options tailored for radio frequency applications. The 103R-822FS specifically addresses needs for stable, high-Q performance in compact surface-mount designs.

Replacement Considerations

Cross-reference with other 103R series variants or equivalent 1010 footprint inductors from other manufacturers if availability is limited. Verify that substitute parts match the 8.2 µH value, 1% tolerance, and physical dimensions.
