Fixed Inductors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and compliance status. Ensure that the procurement channel provides valid traceability for military or established reliability specifications if required by the application. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current production status and availability constraints prior to finalizing orders.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 1 µH is required for high-frequency signal paths. The unshielded nature necessitates careful layout planning to minimize electromagnetic interference coupling with adjacent traces. Verify that the 390 mA current rating aligns with the peak load requirements of the target circuit to prevent saturation or thermal issues during continuous operation.

Fixed Inductors Part Context

This component belongs to the 1025R series, which represents a line of established reliability fixed inductors manufactured by Delevan. The series is characterized by its robust molded construction and consistent performance across wide temperature ranges. These inductors are widely utilized in aerospace, defense, and industrial electronics where long-term stability and proven manufacturing heritage are critical design parameters.

Fixed Inductors Replacement Considerations

Direct substitutes include other 1 µH axial inductors from the same family, such as the 1025R-20K (±10% tolerance) or 1025R-20J (±5% tolerance), provided tighter tolerance specifications are acceptable. Alternative generic equivalents must match the 0.095 x 0.250 inch form factor and ensure comparable current handling capabilities.
