Fixed Inductors Procurement Notes

Verify the specific suffix 'G' against official API Delevan documentation to confirm tolerance and electrical specifications. Ensure the procurement source provides valid RoHS compliance certificates. Cross-reference the manufacturer part number DN7689 or similar distributor codes with the original datasheet to prevent substitution errors.

Fixed Inductors Selection Notes

Select this component when a high-inductance value with tight tolerance is required for axial mounting. Consider the 35 Ohm DC resistance impact on circuit efficiency. Verify that the 40 mA current rating meets the operational requirements of the target application without saturation.

Fixed Inductors Part Context

This component belongs to the 1025R series of fixed inductors manufactured by API Delevan. The series offers various inductance values and tolerances in a standardized axial package. It is designed for reliability in industrial and commercial electronics environments.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 390 µH inductance, 35 Ohm DCR, and axial form factor. Consult API Delevan's official cross-reference lists for verified equivalent part numbers.
