They were film, I made an assumption that since the voltage across the cap was only going to see 30v or so, then they could be rated for a low voltage like 120vac but what got me was the power. So, I gave them a whirl six hey were 3$ a piece. I managed to run a crop under them but they eventually leaked dielectric and became an open circuit. Lesson learned to use a parallel bank of caps.

for that application you should us motor run capacitors rated for at least 250VAC. these are designed to handle high current and continuous operation. in these circuits the peak voltage is a lot higher than the average voltage
