Quoted from G-P-E:Tantalum caps are wonderful caps but don't like two things.
Over voltage.
Reverse voltage.
The fact that it is blowing can be indicative of another problem.
What is the voltage going into cap? And what is the voltage rating of the cap?
the tantalum caps don't age well and the 90s where a bad time for them. I watch all sorts of tech youtube videos where people diag old gear and fix it. Countless gear from the 80s and 90s is not working because of a dead shorted tantalum. Many are a 16v tantalum across a well filtered 5v rail. They cut it off and boom the computer boots up. If the power supply does not shut down from over current. Fireworks.
I have had too many tantalum explode on me. Power up a board that has been shelved for years (like a cheap squeaker). Better put goggles on.
Just bad experience makes me not like them. I imagine today's tantalums are better than the ones in the 80s and 90s... but ask me in 40 years.
Here is a cool repair video I watched the other day for a fancy Data IO burner. (dead tantalum)
