I can get 4.7uF 25V X7R caps for about $0.60 each. Anything larger remotely larger (and not even in X7R) costs about $5.00 each. So I want to stack them. I'm not sure if it's okay to just stack them by soldering them on top of each other on a PCB (I'm don't think they woudl say put either). BUt I was wondering if there was anything that might make it easier? I'd prefer not to have to put them side by side on the PCB just because there would be so many if no stacking was done.
