About products and suppliers

There are also small wind turbines that can be used for applications that include battery charging for traffic warning signs, as well as boat and caravan power. You also have a choice of blade and bladeless options. The bladeless designs generate energy from vibrations alone. Are you looking to source wholesale original transistor 12n50e for your business? Shop from the vast selection from Alibaba.com and take advantage of great deals.


Transistors are the leading discovery of modern electronic processing and computing. With them, it’s possible to control, amplify and turn on and off the signals within a circuit. The circuits have their own complex configuration that determines the function of the components. They can use the transistor as an amplifier, like in the common emitter setup, for example. On Alibaba.com, you have access to wholesale original transistor 12n50e, phototransistors, and much more. Find the right transistor international suppliers for your circuits.


Enjoy a variety of offers for a wholesale original transistor 12n50e, bipolar transistor, JFET transistors, and much more. The transistors function as a gatekeeper for the circuit, letting specific currents flow. They use polarity to impede, enhance, or control the flow of electrons, having a PNP or NPN configuration. These abbreviations refer to the charge of each of their main components: the collector, base, and emitter. Some examples of an NPN transistor include the 2N3904, 2N2222, and BC547, which can all act as amplifiers. As an example of a PNP transistor, the 2N3906 can be cited, also being capable of acting as an amplifier.
