Greetings from a popper roaster and press-potter!
These start/run capacitors are only used with AC motors, so they can't
be the polarized type found in a lot of electronics circuits.
Motor start/run capacitors will be stated as such on the body of the
capacitor, so you won't be left wondering what it actually is.
The difference is that motor start capacitors will have higher
capacitance ratings- ~35 microfarads at perhaps 150 volts AC, and a
short duty cycle, compared to motor run capacitors. The motor run caps
are connected all the time the motor is powered, starting or running, so
they must have a 100% duty cycle.
