HUAREW High Quality BJT Assortment Kit.

The principle of BJT (bipolar junction transistor): The work of a bipolar
junction transistor involves both the flow of electrons and holes,
so it is called bipolar, so it is also called bipolar Carrier transistor This
mode of operation is different from unipolar transistors such
as field-effect transistors, which only involve the drift of a single
type of carrier. The boundary between two different dopant
aggregation regions is formed by a PN junction.

BJT uses: Bipolar transistors can amplify signals, and have better
power control, high-speed work and durability, so it is often used to
form amplifier circuits, or drive speakers, motors and other equipment,
and is widely used Applications in aerospace engineering,
medical equipment and robotics.
