[time-nuts] The Smell of Tantalum in the Morning

[J. L. Trantham]

I fired up a TEK 485 scope over the weekend and was greeted by a similar
event.  Sure smelled like tantalum but turned out it was a sacrificial 10
ohm resistor taken out by a shorted tantalum.

I don't have any equipment that is only 10 years old.

I powered up a 5071A to watch the end of Loran-C today
and was greeted by the special smell that only a mother
board could love.

Does anyone know the history of tantalum capacitor
failures in ten-year old [HP/Agilent] test equipment?
This is not my first. Last one was more like July 4th.

Thanks,
