[Premium-Rx] Nonsmoking Tantalums

[DAVEINBHAM at aol.com]

I have replaced a few dozen shorted tantalums in my 6 pack of Racal 
RA6790/GM's in last 3 years or so.
However, only one was a smoker. Mostly they just short and the +15 power 
supply shuts down. 

Regards,
Dave

Rick,

You might also check if the power supply has any tantalum capacitors in it, 
such as 10uf at 25V match-head epoxy dipped style.  They are sometimes used as 
filters on VCC lines, usually downstream from a 10 ohm 1/4 watt resistor.  I 
don't know why, but in the last five years I have run into literally hundreds 
of shorted ones in Racal, Fluke, Datron and other equipment.  In all cases they 
were adept at sending smoke signals.

The HF-1000 supply sounds almost like a PC power supply...5V, 12V and a power 
good signal line...
