Procurement Notes

Verify the specific package outline number (18, 19, 30, 33, or 39) corresponding to the required mechanical form factor. Confirm that the design does not utilize the restricted part numbers listed in the datasheet header. Ensure proper ESD handling procedures are implemented during assembly due to device sensitivity.

Selection Notes

Select the appropriate package variant based on thermal requirements and board space constraints. The NE68518 uses SOT-343 style, while NE68533 uses SOT-23 style. Verify bias conditions against the typical scattering parameters and noise figures provided for specific collector currents and voltages to ensure optimal circuit performance.
