$begingroup$ thanks for the reply. In my application I have mentioned the maximum usage mostly the power will be less than that around 40W. Is there any chance I am able to use capacitors with higher voltage ratings eg:- 100mF caps with 16V ratings. since the voltage is 12V, they will charge up to 12V, according to the equation 1/2CV^2 …
