I have an application for a supercap in a 1 amp sinewave generator. It would be a 10F, 5V supercap. I can not find power ratings for the supercaps of this size available via Digikey or Mouser.
If I subject my supercap to 1 amp sinusoid for an hour, will it be damaged? If the supercap internal resistance is, say, 50mOhm, that is only 50mW. That is not enough to heat a thing the size of that component above its rated temperature (it is certainly larger than a 1/4 watt resistor), so I am below that limit. Are there other limits to the current rating for supercaps?
The frequency of the current runs from Khz to a few cycles per second. The capacitance is high enough that the voltage limits of the capacitor are not exceeded.
