Fixed Inductors Procurement Notes

Verify the specific suffix designation when sourcing, as variants such as 1026R-04G exist with different tolerances. Confirm that the required inductance tolerance aligns with the ±10% specification of the 1026R-04K model rather than tighter alternatives. Ensure the procurement documentation explicitly references the Delevan manufacturer part number to avoid confusion with generic axial inductors.

Fixed Inductors Selection Notes

Select this component for applications requiring low inductance values in the nanohenry range with moderate current handling capabilities. The unshielded construction may require careful layout consideration regarding magnetic interference. Verify that the axial lead length and diameter fit the target PCB footprint constraints. Consider the operating temperature range limits when designing for extreme environmental conditions.

Fixed Inductors Part Context

This component belongs to the 1026 series of fixed inductors manufactured by API Delevan. The series includes various models differentiated by inductance values, tolerance codes, and current ratings. The 1026R-04K specifically represents a low-inductance variant optimized for high-frequency performance within the general-purpose inductor category.

Fixed Inductors Replacement Considerations

The 1026R-04G is a related variant offering ±2% tolerance instead of ±10%, which may be suitable if tighter precision is required. Other members of the 1026 series should be evaluated based on specific inductance and current requirements. Direct substitution requires verification of physical dimensions and electrical parameters against the original design specifications.
