If you, like us, thought that capacitor orientation only matters for polarized varieties like electrolytic capacitors you should read through this article. [Bruce Trump] looks at why some film ...

With their low equivalent series resistance (ESR), which allows for good ripple-current handling as well as high surge-voltage ratings and self-healing properties, film capacitors are strong ...

I suppose a better question is, when is it not OK to use a higher voltage than original? I know with non-polarized capacitors for use in speaker crossovers, they say higher voltage caps simply allow ...
