108R-123G

Overview

The Delevan 108R-123G is a fixed surface-mount inductor with a nominal inductance of 12 µH. It features an unshielded construction and a nonstandard footprint suitable for compact circuit designs. The component has a maximum DC resistance of 4 Ohms and a current rating of 79 mA. It is designed for RF applications requiring stable inductance in small footprints.

Feature Summary

• Unshielded design for specific electromagnetic interference requirements
• Surface mount technology for automated assembly
• Fixed inductance value for stable circuit performance

Applications

• RF signal processing circuits
• Compact electronic device filtering
• General purpose SMD inductive components

Procurement Notes

Verify the exact package dimensions against your PCB footprint, as this part uses a nonstandard size. Confirm that the 79 mA current rating meets your circuit's operational requirements to prevent saturation. Ensure the unshielded nature aligns with your EMI constraints.

Selection Notes

Choose this component when a 12 µH inductance is required in a small SMD form factor. Consider the 4 Ohm DC resistance impact on power loss. The unshielded type is selected over shielded variants when magnetic field containment is not critical or when cost and height are primary drivers.

Part Context

This part belongs to the API Delevan family of fixed RF inductors. It is characterized by its specific 12 µH value and 79 mA rating. The series offers various inductance options within similar physical constraints for different filtering needs.

Replacement Considerations

Direct substitutes must match the 12 µH inductance, 79 mA current rating, and 4 Ohm resistance. Verify compatibility with the nonstandard footprint or adapt the PCB layout accordingly.
