Fixed Inductors Procurement Notes

Verify RoHS compliance status as documentation indicates conflicting data across sources. Confirm package type availability, as listings show both reel and bulk options. Check manufacturer lead times due to potential supply constraints. Validate specific tolerance requirements against application needs before ordering.

Fixed Inductors Selection Notes

Select this component for applications requiring 22 µH inductance with tight 5% tolerance. Ensure operating currents remain below the 144 mA maximum rating. Verify that the 3.3 Ohm DC resistance fits the circuit design. Consider the unshielded nature for layout spacing requirements.

Fixed Inductors Part Context

Part of the Delevan 1025R series of fixed RF inductors. Shares physical dimensions with other variants in the family. Designed for general-purpose RF applications requiring established reliability. Compatible with standard axial insertion manufacturing processes.

Fixed Inductors Replacement Considerations

Consider 1025R-52K for similar specifications with 10% tolerance instead of 5%. Evaluate 1025-52K if military-grade certification is required. Check 1025R-50J for alternative current ratings within the same form factor.
