Fixed Inductors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm tolerance and current ratings. Ensure that the axial lead length and body dimensions align with the target PCB footprint constraints. Confirm RoHS compliance status for the specific production batch if required by project specifications.

Fixed Inductors Selection Notes

Select this component when a high-inductance value is required in a compact axial package. Consider the 88 mA current limit and 7.3 Ohm DC resistance for power budget calculations. Compare against lower inductance variants in the 1025R series if circuit requirements allow for smaller form factors or higher current handling capabilities.

Fixed Inductors Part Context

This part belongs to the Delevan 1025R series of fixed inductors. The series offers various inductance values ranging from low microhenries to higher ranges, all sharing similar physical dimensions and mounting styles. The 1025R-66F represents the higher inductance end of the standard unshielded lineup.

Fixed Inductors Replacement Considerations

Cross-reference with other 1025R series variants such as 1025R-52K (22 µH) or 1025R-50J (18 µH) if lower inductance is acceptable. Verify equivalent performance from other manufacturers offering axial molded inductors with comparable 82 µH ratings and current limits.
