Low Noise High Gain NPN Bipolar Transistor for Precision Signal Amplification and Control Circuits

The BC849C 215 NPN bipolar transistor is designed for low noise and high gain signal amplification in sensitive analogue and low level electronic circuits. With a collector emitter voltage rating of 30 volt and a continuous collector current of 100 milliampere this transistor provides stable electrical behaviour for amplification stages biasing networks and small signal switching applications. The compact SOT 23 3 surface mount package enables efficient PCB space utilisation and reliable automated assembly.

This transistor is commonly used in audio preamplifiers sensor signal conditioning instrumentation circuits and general purpose analogue designs where low noise performance is critical. The C gain classification indicates higher DC current gain making it suitable for precision applications that require consistent amplification. Its 100 megahertz transition frequency supports clean signal handling in moderate speed circuits used across consumer electronics and industrial control systems.
