Hi,

You need one more piece of info: its value! E.g. 1uf, 0.35uF, 2.2uF, 10uF? 
That is quite important :)

Just don't use too old tantalum caps - they tend to absorb moisture over 
time (when stored incorrectly) - and self destruct as you have experienced..
I just experienced the same while renovating a Tek 475 'scope.

Hi All,

While still appearing to function normally, my PRS10 started to smell:
C900 in the lamp assembly has self destructed.

The SRS parts manual merely says "Capacitor, Tantalum, 35V, 20%, Rad",
so I'd appreciate any advice on what additional parameters I should be
looking at in selecting a replacement.

Thanks,

david
