Procurement Notes

Verify the specific manufacturer source, as API Delevan assets may be managed by other entities. Confirm RoHS compliance status directly with the supplier documentation. Ensure the ordering suffix matches the required tolerance and packaging format. Cross-reference the datasheet revision date to guarantee parameter accuracy for your design cycle.

Selection Notes

Select this component when an unshielded inductor is required for RF frequencies near 1.3 GHz. The 150 nH value and 3% tolerance suit precision tuning circuits. Verify that the 745 mA current rating meets the operational load requirements. Consider the SMD package size constraints against available PCB real estate.
