Fixed Inductors Procurement Notes

Verify the specific suffix 'F' indicates the required tolerance and packaging format against official datasheets. Confirm RoHS compliance status and environmental certifications prior to ordering. Ensure the axial lead length and diameter match the target PCB layout requirements. Check for established reliability specifications if the application demands extended operational life.

Fixed Inductors Selection Notes

Select this component when precise inductance control is necessary for RF tuning. The 18 µH value and 30 MHz self-resonant frequency define its usable bandwidth. Consider the 149 mA current rating to prevent saturation in the target circuit. The unshielded nature requires careful placement to minimize electromagnetic interference with adjacent components.

Fixed Inductors Part Context

This part belongs to the Delevan 1025R series of fixed RF inductors. The series offers various inductance values with different tolerance codes. The 1025R-50F specifically denotes the 18 µH variant with 1% tolerance. It shares physical dimensions with other members of the family but differs in electrical parameters.

Fixed Inductors Replacement Considerations

The 1025R-50J serves as a substitute option within the same series, offering 18 µH inductance with ±5% tolerance and identical physical dimensions.
