What is this capacitor?
« on: April 27, 2018, 08:31:30 pm »
I’m looking here at a capacitor from an older HealthKit oscilloscope. Would someone be able to explain what these markings are, and what the terminals correspond to? There seem to be multiple terminals on the bottom, not connected to the chassis of the cap, which are identified with different symbols. What’s going on here?

Looks like an electrolytic capacitor with multiple capacitors inside the can. I just happened to watch Mr Carlson's Lab that used one. Watch the link for an explanation.

Yep just as mbless says.
The symbols shown alongside the marked values indicate the pins to which those values apply and are stamped on the pins underneath.
 
They're polarized and share a common negative.

Also, you may wish to consult the schematic -- should be easy to find, Heathkit stuff is well documented -- which will show what that capacitor is and how it's connected. :)
