Forum members, Am trying to spec out some small value capacitors to be placed across unrectified mains potentials. These caps are rated at dc potentials way beyond the peak of the ac bus potential, but they carry no ac rating.
What are the issues here? The cap should not breakdown at ac mains potential, so what information does an ac rating provide? Is it related to surge potentials that can appear on ac mains? Thank you and happy Labor Day to those members are the west side of the Pond.
