Procurement Notes

Verify the specific ordering suffix, such as -T1-A, against the manufacturer's official documentation to ensure correct tape-and-reel packaging configuration. Confirm RoHS compliance status and active production status directly with CEL or authorized distributors before finalizing procurement orders to avoid supply chain discrepancies.

Selection Notes

Select this component when designing circuits requiring NPN RF transistors with 12GHz cutoff frequencies and 6V voltage ratings. Ensure the application board supports SOT-343 footprints and that thermal management accommodates 200mW dissipation. Validate biasing requirements align with the specified 30mA/3V test conditions for optimal gain performance.

Part Context

This part belongs to the CEL NE6xxx series of bipolar RF transistors. These devices are engineered for radio frequency applications, offering a balance of gain, voltage handling, and high-speed switching. The NE67818-A specifically targets microwave bands, distinguishing itself within the family through its 12GHz operational limit and low-voltage compatibility.

Replacement Considerations

Cross-reference with other NPN RF transistors from CEL featuring similar 12GHz specifications and SOT-343 packages. Verify pinout compatibility and electrical parameters like Vceo and fT before substitution to maintain circuit integrity.
