Little know fact, a small tantalum capacitor can be used as a model rocket
igniter in a pinch :-) In early 2000 when I was at NetApp, NetApp was
selling filers to IBM to re-badge as their own. IBM got on a 'no tantalum'
war path (apparently they had been the source of a number of bad events in
the field) and so we worked with them to remove every single tantalum
capacitor from the equipment. It was quite the project.

Thanks. I had no idea that tantalum capacitors had polarity though, I
thought that was only electrolytics. The board has "+" markings for
'Tantalums' are a subset of electrolyticss (the full name is 'tantalum

electrolytic capacitors'.
Conntecting a tantalume capacitor backwards is not something you'll
forget in a hurry. It will explode and probbly catch fire. It smells
terrible.
electrolytics, but none for the tantalum ones.
Are you sure they have
polarity?
Yes I am darn sure...
