Fixed Inductors Procurement Notes

Verify RoHS compliance status directly with the manufacturer, as historical data indicates potential variations. Confirm the specific ordering suffix matches the required tolerance and packaging configuration. Ensure the requested quantity aligns with standard factory reel sizes to avoid partial order complications. Cross-reference the datasheet revision date to guarantee parameter accuracy for your specific design requirements.

Fixed Inductors Selection Notes

Select this component when a 15 µH inductance value with high precision is required for axial mounting. The 157 mA current rating dictates suitability for low-power RF stages rather than high-current power supplies. Compare the 2.8 Ohm DC resistance against circuit loss budgets. Verify that the unshielded nature does not interfere with nearby sensitive traces or components in dense layouts.

Fixed Inductors Part Context

This part belongs to the Delevan 1025R series of general-purpose RF inductors. The series offers various inductance values and tolerances using similar molded axial packages. It serves as a legacy alternative to surface mount options when mechanical robustness and through-hole assembly are prioritized over miniaturization constraints.

Fixed Inductors Replacement Considerations

Direct substitutes include other 15 µH axial inductors with comparable current ratings and physical dimensions. Verify pin compatibility and thermal characteristics before swapping manufacturers. Consider the 1025R-48J variant if a wider tolerance range is acceptable for cost optimization.
