Frequently Asked Questions

Q: What is a TO-92 transistor package and why is it commonly used?

A: The TO-92 is a small, three-legged through-hole plastic package widely used for low-power bipolar junction transistors (BJTs). It is easy to insert into breadboards and solder onto PCBs, making it a favourite for hobbyists, students, and engineers working on amplifier, switching, and signal-processing circuits.

Q: What is the difference between NPN and PNP transistors in this kit?

A: NPN transistors (e.g. 2N2222, 2N3904, S9013, S9018) are switched on by applying a positive voltage to the base, while PNP transistors (e.g. 2N3906, A1015, S9012, S8550) are switched on by pulling the base voltage below the emitter. This kit includes both types so you can design complementary circuits, push-pull amplifiers, and more.

Q: Are these transistors compatible with Arduino and Raspberry Pi projects?

A: Yes! The low-voltage, general-purpose transistors in this kit (such as the 2N3904, S8050, and S9013) are ideal for driving LEDs, relays, and small motors from the GPIO pins of Arduino, Raspberry Pi, and similar microcontroller platforms.

Q: How are the transistors packaged — will they arrive organised by value?

A: The kit contains 600 transistors across 15 values (40 pieces each). Components are typically grouped or bagged by value to help you sort and store them easily in a component organiser or parts box.
