NE68518-T1-A

Overview

The CEL NE68518-T1-A is an NPN radio frequency bipolar junction transistor manufactured by CEL. It is housed in a compact SC-82A (SOT-343) four-pin surface-mount package, designated as Case 18. The device is engineered for RF applications with a maximum collector-emitter voltage rating of 6V and a continuous collector current capacity of 0.03A. This component serves as a specialized active element within high-frequency circuit designs requiring small form factor integration.

Feature Summary

• Utilizes a low-profile SOT-343 surface-mount footprint to facilitate dense PCB layout and automated assembly processes.
• Constructed as an NPN silicon BJT optimized for stable operation in radio frequency signal paths.
• Rated for a 6V maximum collector-emitter breakdown voltage suitable for low-voltage portable electronics.

Applications

• RF amplifier stages in wireless communication modules
• Signal processing circuits in mobile devices
• Low-noise amplification in consumer electronics

Procurement Notes

Verify the specific suffix 'T1' against official manufacturer documentation to confirm tape-and-reel packaging specifications. Ensure the part number matches the exact electrical ratings required for the target RF design. Cross-reference the SC-82A package dimensions with board layout constraints prior to procurement.

Selection Notes

Select this component when a low-voltage NPN RF transistor is required in a miniature SOT-343 package. Confirm that the 6V voltage rating and 30mA current limit align with the circuit's operational parameters. Evaluate thermal management requirements given the small surface-mount case size.

Part Context

This part belongs to CEL's portfolio of discrete RF transistors designed for wireless infrastructure and handheld devices. The NE68518 series provides standardized performance for RF front-end applications. The T1 suffix typically indicates specific reel packaging for surface-mount technology assembly lines.

Replacement Considerations

Consult official substitution guides for compatible NPN RF transistors in SOT-343 packages. Verify pinout compatibility and electrical parameter equivalence before replacing the original component in existing designs.
