<DIV><FONT face=Arial size=2>I work for an electronics manufacturer that builds
RF test equipment. When they're good, tantalum caps are very, very
good. When they're mistreated, they are very, very bad. In my time
I've witnessed or personally blown about every component that ever existed, but
nothing is as scary as a tantalum scorned.</FONT></DIV>

<DIV><FONT face=Arial size=2>When an electrolytic blows, usually because of
reversed leads, you get a shower of confetti. If it's oil filled, you
also get an evil fishy smell that lasts *forever*, and there's always the
aluminum casing that you have to dodge.</FONT></DIV>

<DIV><FONT face=Arial size=2>A tant, on the other hand, gets Hot. Willy
peter hot. Our bench tops can take about anything - lay your soldering
iron tip on it for quite a long time and it'll hardly phase these
benchtops. I've seen a tantalum burn right through them like they were
butter. Seriously. And they will go airborne. But this is
usually from reversed leads. Otherwise, if they "naturally" go bad,
they'll just short without the fireworks.</FONT></DIV>

respect they deserve.</FONT> <FONT face=Arial size=2> Watch the
