Description
Transistors are powerful electronic switches. These NPN transistors are very useful whenever we need to control medium-power electronics such as small motors, solenoids, or IR LEDs.
Each transistor is a general purpose amplifier, model PN2222 (same pinout as the 2N3904) and has a standard EBC pinout. They can switch up to 40V at peak currents of 1A (not continuously, just peak!), with a DC gain of about 100. They are you most general type of transistor and works great as an allrounder.
