Hey everyone. This is probably a pretty basic question for some but I'm not sure of the answer. Basically, I'd like to know how to determine a capacitor's power dissipation capability. I did a quick Google search but didn't find any clear answers. One site said that ESR was a measure of power dissipation capabiltiy and another said that ripple current was.
I'm thinking about using this 25V 47µF cap in an LED circuit. I simulated the circuit and the cap's power dissipation is going to vary. The graph of power dissipation essentially looks like a full wave rectified sine wave at 60 Hz and according to simulator, the cap will have a peak power dissipation of 360 mW. How do I know which caps would be suitable? Thanks in advance for the assistance.
