please explain to me (i'm sure bonez will) why in BC's SX280 premade kit, you're replacing 16V 1500s with 16V 330's? I know voltage is better if its the same, but taking the capacitance down that much?

Re: less then half rule?
There is no rule.
The reduction in capacitance is only specific for VRM circuits and their controller ICs, and only applies when using a polymer capacitor with significantly lower ESR than an aluminium electrolytic.
I believe that this comes straight from the application note of the controller IC itself.
I don't know if it applies to ALL VRM ICs though or just some specific models, but I'm sure PCBONEZ can clear that part up."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"
