Fixed Inductors Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm that the physical dimensions, lead spacing, and core material match the documented parameters for the 0819R-74H. Ensure compliance with relevant environmental standards if required for the specific application environment.

Fixed Inductors Selection Notes

Select this component when an unshielded axial inductor with high inductance is required for RF or general-purpose applications. Consider the 16 Ohm DC resistance and 54.5 mA current rating to ensure compatibility with circuit power requirements. Verify that the lack of shielding does not interfere with nearby sensitive components.

Fixed Inductors Part Context

This part belongs to the API Delevan 0819R series of molded unshielded RF coils. These inductors are characterized by their cylindrical tubular shape and axial leads, distinguishing them from surface-mount alternatives like the 2512R series. They are engineered for reliability in standard through-hole PCB layouts.

Fixed Inductors Replacement Considerations

Cross-reference with other 0819R series variants such as 0819R-54H for different inductance values. Ensure any substitute maintains the same axial footprint and voltage ratings. Verify that alternative manufacturers offer comparable Q-factor and self-resonant frequency characteristics.
