Procurement Notes

Verify the specific manufacturer designation, as sources list both API Delevan and Delevan. Confirm RoHS compliance status through official documentation. Ensure the ordering suffix matches the required tolerance and packaging format. Cross-reference datasheets to validate electrical parameters against your schematic requirements before procurement.

Selection Notes

Select this component when a low-inductance value near 15 nH is required for high-frequency signal paths. The unshielded design may necessitate careful layout planning to prevent crosstalk. Verify that the 1.11 A current rating meets the operational load. Consider the 2.2 GHz self-resonant frequency limit to ensure performance stability at the target operating frequency.
