Fixed Inductors Procurement Notes

Verify the specific ordering suffix against official API Delevan documentation to ensure correct tolerance and packaging specifications. Confirm RoHS compliance status as requirements vary by production batch. Check manufacturer datasheets for updated environmental declarations and REACH SVHC information prior to final procurement decisions.

Fixed Inductors Selection Notes

Select this component when an unshielded axial inductor with 39 µH nominal value is required. Ensure the 125 mA current rating meets circuit load requirements. Verify that the 2.5 MHz self-resonant frequency aligns with the target operating band. Consider thermal management capabilities within the specified -55°C to +105°C operational range.

Fixed Inductors Part Context

This part belongs to the Delevan 1025/R series of molded unshielded RF coils. The series offers various inductance values in a consistent axial package format. These components are designed for reliability in radio frequency environments where shielding is not mandatory or feasible.

Fixed Inductors Replacement Considerations

Cross-reference with other 1025R series variants for different inductance values. Verify pin compatibility and electrical parameters before substituting with generic axial inductors.
