Transistors are fantastic little components that are good for an exceptionally wide range of different applications, depending on how they are integrated into circuits. And from simple on/off switching to ultra-fast PWM-level switching, as well as acting as logic gates within an analog circuit, you can find Transistors assisting almost all circuits in the world due to their ease of use and simple but very reliable behaviour.

These 2N3904 NPN General Purpose Transistors are very common in the world of Electronics, and feature a dynamic range that extends up to 100mA as a switch and 100MHz as an amplifier, and this wide dynamic range is what makes it great for a very wide selection of applications. It is designed in an NPN configuration, which of course means that it responds to positive signals for switching, with an operational frequency of 300MHz for fast response and effective current gain.

Please Note: These units are priced individually but sold in minimum order quantities of ten (10), so as to save on shipping costs and reduce the overall price for each unit.
