How to calculate capacitor''s Power Rating?

I would say focus more on the voltage rating. Capacitors don''t really dissipate a lot of real power when used well under their voltage rating. They do though however generate reactive power but that has nothing to do with real power and hence heat. Voltage rating is more important than ''power'' rating. $endgroup$ –
