dual value motor run caps

I picked up a few 2 value motor run caps. One lead says "fan" and the other says "Herm" and then there's common.

I'm guessing "fan" is the smaller value and "herm" would be the bigger?
I came to that conclusion because I'm thinking maybe some motors have a separate fan motor. So, the fan would need the small value, and the big motor would need the large value.

Is that correct?
