I am thinking of replacing some aluminum electrolytic capacitors on a 1980's vintage computer board. While I know that caps must be replaced with same or higher voltage rating, I was wondering if there are any negative effects or reasons NOT to bump up capacitors' voltage ratings. The original cap I was thinking of replacing is very messy looking and has probably leaked out onto the board. It is 16v, but I found some 25v caps for a cheap price. Considering dieletric, plate separation, internal resistance and the like, are there really any negative effects that could result from using a higher voltage rating?
