Procurement Notes

Verify the specific manufacturer part number against official API Delevan documentation to confirm electrical parameters and physical dimensions. Ensure compatibility with surface mount assembly processes. Check for RoHS compliance status through official datasheets rather than distributor summaries. Confirm package type and reel specifications directly from the manufacturer's ordering information.

Selection Notes

Select this component based on its 27 nH inductance value and 925 mA current rating requirements. Consider the unshielded nature when layout spacing is critical to avoid interference. Verify that the 114 mOhm DC resistance meets circuit loss constraints. Ensure the 1.22 GHz self-resonant frequency aligns with the operating bandwidth of the target application.
