Procurement Notes

Verify the manufacturer part number against official API Delevan documentation to confirm specifications. Ensure compatibility with standard reflow soldering processes. Check for RoHS compliance status through authorized distributors. Confirm reel packaging quantities align with production requirements before ordering.

Selection Notes

Select this component when a precise 12 µH inductance is required in compact RF designs. Consider the low current rating of 160 mA for power constraints. The unshielded design necessitates careful layout planning to avoid crosstalk. Verify that the 24 MHz self-resonant frequency meets the operational bandwidth needs.

Part Context

This part belongs to the 103/R series of RF inductors from Delevan. These components are designed for high-frequency applications requiring stability. The series offers various inductance values with tight tolerances. They utilize standard surface-mount technology for automated assembly integration.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure replacement parts match the 12 µH value, 1% tolerance, and 2.54 x 2.54 mm footprint. Verify equivalent current ratings and self-resonant frequencies.
