Fixed Inductors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and RoHS compliance status. Cross-reference the part number with authorized distributors to ensure authenticity and availability. Confirm that the axial lead configuration matches the target printed circuit board layout requirements prior to final procurement decisions.

Fixed Inductors Selection Notes

Select this component when a high-inductance value of 180 µH is required alongside a low current rating of 57 mA. The 17-ohm DC resistance must be compatible with the circuit's power loss constraints. Ensure the physical dimensions fit the available board space and that the unshielded nature does not interfere with nearby sensitive components.

Fixed Inductors Part Context

This component belongs to the 1025R series of fixed inductors manufactured by API Delevan. The series utilizes a standardized axial form factor with molded bodies. This specific model represents a higher inductance variant within the family, distinguished by its unique tolerance code and current handling capabilities compared to lower inductance counterparts.

Fixed Inductors Replacement Considerations

Direct substitutes include other 180 µH axial inductors from the same manufacturer series, such as the 1025R-74J or 1025R-74K, provided their respective tolerance codes align with the design requirements. Verify that alternative parts maintain the same 57 mA current rating and 17 ohm maximum DC resistance specifications.
