Description
The BC549 is a high-performance NPN bipolar junction transistor (BJT) specially designed for general-purpose low-noise signal amplification and switching applications. Known for its superior noise performance and reliable operation, it is a preferred choice for audio and small-signal processing circuits.
With a maximum collector current of 100mA and a voltage rating of 30V, the BC549 is ideal for low-power applications such as pre-amplifiers, audio circuits, and basic switching tasks. Its gain (hFE) ranges from 110 to 800, ensuring efficient amplification of weak input signals. The transistor’s compact TO-92 package makes it perfect for breadboards and PCBs, simplifying circuit integration for students, hobbyists, and professionals.
The BC549 is widely used in projects requiring precision and minimal signal distortion, making it an essential component for audio enthusiasts and general-purpose electronic designs.
