Procurement Notes

Verify the specific suffix -T1B-A against official datasheets to confirm tape-and-reel packaging and binning specifications. Confirm that the component meets RoHS compliance requirements for your target market. Ensure the ordering code matches the exact package outline and marking codes provided by the manufacturer.

Selection Notes

Select this component when designing circuits requiring high gain bandwidth and low noise figures in the UHF and microwave ranges. Consider the thermal resistance and power dissipation limits relative to your heat sinking strategy. Evaluate the S-parameter data for impedance matching network design to optimize stability and gain at your specific operating frequency.

Part Context

This part belongs to the NE681 series of NPN silicon transistors manufactured by California Eastern Laboratories (CEL). The series includes various package options such as chip, Micro-X, and several SOT styles, all sharing similar core electrical characteristics optimized for RF amplification.

Replacement Considerations

Direct replacements within the same series include NE68133 variants. Cross-manufacturer equivalents may exist but require verification of pinout compatibility, gain bandwidth product, and noise figure specifications.
