It features a maximum DC resistance of 108 mΩ and supports a maximum DC current of 950 mA. The component exhibits a minimum Q factor of 50 and a self-resonant frequency of 1.8 GHz. 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 self-resonant frequency suitable for RF applications
• Standard two-terminal SMD termination style

Applications

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

Procurement Notes

Verify the specific manufacturer designation, as sources list both API Delevan and Delevan. Confirm RoHS compliance status through official documentation. Ensure the package dimensions match the required PCB footprint. Check for any specific handling requirements associated with unshielded components during assembly.

Selection Notes

Select this component when a low-inductance value near 22 nH is required for high-frequency operation. The unshielded design may necessitate careful layout to prevent crosstalk. Verify that the 950 mA current rating meets the circuit's peak load requirements. Consider the 1.8 GHz self-resonant frequency limit for signal integrity.
