It features a maximum DC resistance of 740 mΩ and supports a maximum DC current of 360 mA. The component has a minimum Q factor of 22 and a self-resonant frequency of 74 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 minimal magnetic interference
• High precision 1% inductance tolerance
• Surface-mount design for automated PCB assembly

Applications

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

Procurement Notes

Verify the specific manufacturer source, as API Delevan assets have transitioned. Confirm RoHS compliance status directly with the supplier, as documentation varies across distributors. Ensure the ordering suffix matches the required reel quantity specifications for production integration.

Selection Notes

Select this component when a precise 1.2 µH value is required in a compact 1010 footprint. The low DC resistance and defined current rating suit power-sensitive RF stages. Verify that the unshielded topology aligns with the board's electromagnetic compatibility requirements.

Part Context

This part belongs to the 103/R series of fixed RF inductors manufactured by Delevan. These components are designed for high-frequency applications requiring stable inductance values in small form factors. The series typically utilizes phenolic core materials for consistent performance.

Replacement Considerations

Cross-reference with other 1.2 µH SMD inductors in the 1010 package size. Verify that substitute parts meet the same 740 mΩ DC resistance and 360 mA current handling limits to ensure circuit continuity.
