I have a nicely-spec'd wireless router that doesn't work any more. (Sorry, I don't have a schematic, but it's an Asus RT-N16.) I popped it open and found that it has one capacitor with a bulging top. It's labeled 16V 680uf, but I don't have a capacitor with those exact specs. But as long as I find another capacitor with roughly the same capacitance, I should be able to substitute that, right?
Q=CV Q=16v*680uf Q=10880C
I have a ton of random junk that has various capacitors with other specs. For example, one is labeled 35v 470uf.
So, suppose I want to substitute this 35v capacitor.
C=Q/V C=10880C/35v C=311uf
Since the proposed substitute capacitor's 470uf > 311uf, is it likely that this substitution will work, or is it the case that I'm oversimplifying this and need to find something with closer specs printed on the side?
