Modern capacitor over voltage, how high and for how long?

[Sorento]

Voltage rating - Voltage DC or Voltage AC?

It's interesting that Wima caps are rated with a DC and an AC voltage. Thus a 600V wima is typically 600Vdc but not AC, which is typically rated for less AC such as 400Vac --

Wima just reminds you that AC voltages are usually given as RMS numbers.
Other manufacturers simply assume that you know that 400V rms sinusiodal waveforms have 1.4 x peaks which requires a 600V rating ...

benchbaron,

It is OK, no problem.

. . . I think most vacuum tube amplifiers are more reliable than computer software, etc.

If that is a reply to my other mashed post then you are SPOT on !!!

I am not aware of any capacitor being infected with a virus.
