Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required package style and lead-free specifications. Request original datasheets to validate electrical parameters against current production standards before integration into final designs.

Selection Notes

Select this component when low noise performance and high gain are critical requirements within the S-band and C-band frequencies. Ensure the biasing circuit supports the specified low voltage and current operating points to maximize efficiency. Consider thermal management capabilities relative to the total power dissipation limits defined in the absolute maximum ratings section.

Part Context

This part belongs to the NE680 series of NPN epitaxial silicon transistors manufactured by California Eastern Laboratories (CEL). The series includes various package options such as chip, SOT-343, and SOT-23 styles. While the NE680 series is noted for cost-effective high-frequency performance, certain variants may be marked as not recommended for new designs.

Replacement Considerations

Consult the manufacturer's sales office for details on obsolete or restricted parts within the NE680 series. Cross-reference with the NE681 series if higher collector current capabilities are required for the application.
