• Surface mount configuration with standard two-lead termination
• Optimized for radio frequency signal processing tasks

Applications

• RF choke circuits
• Signal filtering in communication modules
• Impedance matching networks

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS compliance details via official documentation. Check for valid substitute part numbers from API Delevan or successor manufacturers. Ensure storage conditions maintain component integrity prior to assembly.

Selection Notes

Select this component for low-inductance RF requirements where shielding is not critical. Evaluate thermal performance against the 620 mA current limit. Compare physical dimensions against available PCB real estate. Consider lead-free soldering compatibility for modern manufacturing processes.

Part Context

This part belongs to the Delevan 105 series of fixed inductors. It represents a legacy surface mount solution for RF engineering. The manufacturer API Delevan specializes in passive components for high-frequency applications. This specific model serves as a historical reference for older electronic designs requiring precise small-signal inductance.

Replacement Considerations

DigiKey lists this product as obsolete. Verify compatible substitutes through official manufacturer channels. Cross-reference electrical parameters such as inductance, current rating, and DC resistance when selecting alternatives.
