Don't even think of using them.

They're dipped-tantalum capacitors. The positive lead is the one with
the dot.

Problem is, these tend to fail hard and often. They short out all the
time. Either at random or just after a mild overvoltage incident.

And the color codes are hard to interpret.

Which is good for repair guys like me-- I've bought dead oscilloscopes
and calibrators for like $5. Only problem was one to seven shorted
caps, just like the ones you pictured.
