Description
Product Overview
The BOJACK 2N3904 NPN transistor is a versatile, general‑purpose BJT that meets the demanding needs of both hobbyists and professional engineers. With a maximum collector‑emitter voltage of 60 V, a continuous current rating of 0.2 A, and a transition frequency reaching 300 MHz, this device offers a balanced combination of voltage handling, current capability, and high‑speed performance. Packaged in a rugged, resealable plastic case containing 200 individual transistors, the product ensures easy storage, quick access, and protection against static discharge. The transistors are housed in a TO‑92 style package, a widely recognized form factor that fits standard breadboards and PCB footprints, simplifying integration into a wide range of circuits ranging from simple switching applications to more complex analog amplification stages.
Usage
These transistors excel in environments where reliability and repeatability are paramount. Typical use cases include low‑power amplification in audio circuits, switching regulators for power management, signal conditioning in sensor interfaces, and as building blocks in educational laboratory experiments. The 60 V rating makes them suitable for small‑signal applications that operate below typical automotive or industrial voltage levels, while the 300 MHz frequency response supports modern high‑speed digital logic interfacing and RF front‑end prototypes. Engineers designing portable devices, hobbyists constructing Arduino‑compatible modules, and educators preparing lab kits will find the 200‑piece quantity especially convenient for batch testing, inventory stocking, and rapid prototyping.
