Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration, as variations such as reel or bulk may exist. Confirm RoHS compliance status directly with the manufacturer, as historical data indicates non-compliance for certain variants within this series. Ensure the selected part number matches the required inductance value and current rating for the target application before finalizing procurement.

Selection Notes

Select this component when a precise 12 µH inductance with minimal deviation is required in RF designs. The unshielded nature necessitates careful layout planning to avoid magnetic coupling with adjacent components. Verify that the 126 mA current limit aligns with the operational requirements of the circuit to prevent saturation or excessive heating during continuous operation.

Part Context

This component belongs to the Delevan 0819 series, which specializes in high-quality, molded RF inductors. The series offers various inductance values tailored for radio frequency applications, emphasizing stability and precision. The 0819-50F specifically addresses needs for higher inductance values within the axial form factor, maintaining the series' reputation for consistent performance in sensitive electronic systems.

Replacement Considerations

Direct substitutes within the same series include the 0819R-50F, which shares identical electrical specifications but may differ in manufacturing revisions or minor physical attributes. Cross-series replacements require careful verification of inductance, tolerance, current rating, and self-resonant frequency to ensure functional equivalence in the specific RF application.
