Fixed Inductors Procurement Notes

Verify the exact manufacturer part number against official API Delevan documentation to confirm specifications. Ensure compatibility with established reliability requirements for your specific application environment. Cross-reference datasheet parameters such as inductance, tolerance, and current ratings prior to integration. Confirm RoHS compliance status if required by your manufacturing standards.

Fixed Inductors Selection Notes

Select this component when a high-inductance value of 390 µH is required in an unshielded axial form factor. Consider the 40 mA current limit and 35 Ohm DC resistance for power handling constraints. The 25 MHz self-resonant frequency defines the upper operational limit for effective inductive behavior. Evaluate physical dimensions against available PCB space for through-hole placement.

Fixed Inductors Part Context

This component belongs to the 1025R series of RF inductors manufactured by API Delevan. The series offers various inductance values tailored for radio frequency applications. These inductors are characterized by their molded construction and axial leads, distinguishing them from surface-mount alternatives. The 1025R-82K specifically addresses needs for higher inductance within this standardized package format.

Fixed Inductors Replacement Considerations

Consult official API Delevan cross-reference lists for verified substitute part numbers. Generic equivalents may not match the specific iron core material or established reliability standards. Verify that alternative components meet the same 390 µH inductance, 40 mA current rating, and dimensional constraints.
