![]() ![]() At a ratio of 100 times input to output, you can see how you can build a really strong amplifier in short order, with just a handful of components. You can then take the output of one transistor and feed it as the input to the next one, and so on, eventually multiplying the amplification as you need it. You have a few resistors here and there, but basically the circuit diagram is mostly a bunch of these 2N3904 NPN transistor components strung along together to create the increased amplifier effect.Įach transistor creates a certain amplification effect. So what that means is that the rest of the circuit design is fairly simple. The transistor does most of the work for you. 2N3904 MMBT3904 PZT3904 P D Total Device Dissipation Derate above 25☌ 625 5.0 350 2.8 1,000 8.0 mW mW/☌ RJC Thermal Resistance, Junction to Case 83.3 ☌/W RJA Thermal Resistance, Junction to Ambient 200 357 125 ☌/W Device mounted on FR-4 PCB 1.6' X 1.6' X 0.06. The transistor is the real workhorse for a lot of audio components. I used to mess around with audio electronics some time ago. I think that, theoretically, you could probably buy a single IC chip that would do the job for you, rather than choosing to buy transistor components to get the same results. Thus, its collector and emitter pins remain in open mode when you hold the base pin to. Este dispositivo incluye soporte de soldador, pinzas de cocodrilo, soporte para carrete de hilo de estaño, caja con flux para soldadura, y limpiador metálico en seco de puntas. ![]() I would guess that in most modern applications you don’t really need to string along a whole bunch of transistors to get the same result.įor example, I know that IC chips can contain hundreds of transistors in them.
