I can do the math for power dissipation if it was DC current at 33k, that would be a little less than half a watt. AC would be even less I think, since the duty cycle is less, but I’m not entirely sure about that. It sounds OK to me though.

yes well that sort of thing is always a challenge ;) Perhaps they should be instructed not to play with the ceiling fan speed ;) Though that sort of thing rarely works either.

Those are the values I used. But I realize in my head I was treating them as resistors when adding up the parallel value and not as capacitors which actually increase their capacitance when in parallel… It seemed to work though, I’ll have to revisit that and make sure.

Must be non-polarized and plenty of overhead on the voltage ratings.

Thanks,
