correct me where i`m mistaken.
capacitor temperature is determined by the power of heating loses in it -
right?
this power is determined from reactive power & dissipation factor - it`s
their multiplication - right?
reactive power (at given current ratings) is proportional to the reactive
resistance of the cap - right?
reactive resistance of the cap at 1 khz is 500 times more than at 500 khz -
right?
so then loses at the same RMS at 1 khz would be 500 times more than at 500 khz.

Your not coiling unless your blowing capacitors! Then when you get things
worked out to where the capacitors stop blowing, you start blowing
transformers.
