Procurement Notes

Verify the specific ordering suffix E6327 against official Infineon documentation to confirm reel specifications and packaging details. Confirm component authenticity through authorized channels as the datasheet indicates published information is not a guarantee of characteristics. Ensure handling precautions are observed due to electrostatic discharge sensitivity.

Selection Notes

Select this component when designing circuits requiring a transition frequency up to 30 GHz and a noise figure as low as 0.9 dB at 1.8 GHz. Consider the TSFP-4 package constraints and the 250 mW power dissipation limit relative to thermal management requirements. Evaluate the 4.5 V collector-emitter voltage rating against system supply voltages.
