I am designing a board to be used outdoors and the enclosure can get quite warm in the sun. Therefore I want to avoid using electrolytic caps to ensure long life of the board. The electrolytics were to be used for decoupling and be around 47uF.
From research on the web, it would seem that I can use a few ceramics in series to get the same capacitance (while lowering the ESR too) and get the robustness/reliability that I am after.
Are there any drawbacks to using several ceramics rather than one big cap? (other than space).
