I was testing my auto reverse model train controller and let the smoke out of a cap. Well, more like yellow snot, all over my breadboard.
Here is the relevant piece of my diagram.
I wanted to test that I was getting 5v out of the regulator. I was. 4.98v by my DMM from point A to point B.
Hmm… Something smells hot. Yup cap gettin hot. Tried to unplug the transformer but not it time.
I triple checked polarity before and after the Genie escaped and am reasonable sure I got it right.
Then I saw the voltage rating on the cap. 330uF 10V. The others in my sample kit are 50v and various numbers of farads.
If I feed 20VAC into the diode bridge and put a 330uf 10v cap across, is the expectation smokey?
I ordered some others in various voltage ranges.
Will 330uf 35V do the trick?
