PNP transistor not working 2. Sign up using Facebook. So perhaps 15 C rise over ambient? Now, this is a bit of a compromise. Xatasheet there are NPN transistors that can work for this relatively low current fan, generally load switching is best done using an NFET. Something on the order of this: However, before atempting to make anything definitive, I would appreciate if you could tell me if I did everything correctly ie,i’m not going to damage my Pi.
Thanks in advance for your help!
Often, it’s lower than that, but sometimes it may be a little higher. The transistors I have several pieces in each case: ModelSim – How to force a struct type written in SystemVerilog? Distorted Sine output from Transformer 8. HerrCrazi If you use the first circuit, the values are both important. Part and Inventory Search. But that’s probably okay. Choosing IC with 2n432 signal 2. Once again, thanks a lot for you help!
Check if your datashet is in the list: So perhaps it is okay. Thank you very much for this great answer! So I need to have a transistor acting as a switch controlling the fan power.

I’d prefer still more base current. Theres still some small details Datasheet barely understand, but I’m sure I’ll understand them as dxtasheet as I’ll take the time to retry doing the math on my own which is actually the best way to understand something. Input port and input output port declaration in top module 2. But it would help to know what you think you follow, already, because that could save me time. So it probably will be fine, as shown.
I did some tests with one of them, and at this point, it seems to work perfectly. The math I chose could use more explanation. If you want to search a similar part from the parts available at your local shop, compare Vgs off and Idss. Should I mount it exactly like a standard NPN transistor? Dec 242: You could measure it, too. The problem is that the GPIO pin aren’t powerful enough to drive the fan plus it would be dangerous for the Pi itself.
I actually have some transistors at hand, but I’m not sure if they are suitable for this use, nor which one of them would fit the best. But it is all worth a try.

You could also consider a fan with a PWM control input.
AF modulator in Transmitter what is the A? I think at that point I understood almost everything you explained me. But R1 can be most anything that is as large as or larger than 1k or so.

Thank you for that really quick answer! Must the values of these resistors be exactly as you said, or would it be possible to use only one of them? Dec 248: At least, I think so. Digital multimeter appears to have measured voltages lower than expected.
So that’s the number I’m going with. How reliable is it?
