Hey there, so like the title says I accidentally bought some SMD 10uF caps that are non-polar when I wanted polarized ones.
My question is, could they still work? I'm still learning a lot about electronics and I'm particularly unfamiliar with capacitors it seems, so I could really use some help from somebody a bit more knowledgeable.
So what I'm trying to do is set up an Arduino system as layed out by this tutorial: http://arduino.cc/en/Main/Standalone
The only difference is I'm trying to do it with SMD components for a project I'm working on. I'm not really too sure what the 10uF caps around the 5v regulator are for, so can anybody tell me if there's any way non-polar caps could do the trick here?
Sorry, I feel like a dingus having to ask a question like this... I also really hope this works because I don't really have the time to wait for new components to arrive if I have to order some.
No issue in this application, the cap by the regulator is for ripple rejection. Prevents the voltage from changing on your output should the VIN start to fluctuate. Large value stops large changes small value stops small changes.
In dc applications non polarized are generally better but larger and more expensive to use. In ac applications like amplifiers you may want both or only non polarized.
You'd never run into this but there are very rare cases where polarized is required to get the desired response and vise Vera's where you would think that a polarized would work as it's dc but must use a non polerized ,which is more common.

maybe it's because english is not my mother tongue, but I can't get what you mean here
edit : oups, sorry, forget it, with ".... vice versa...." , it makes sense
