Subject: [time-nuts] Electrolytic Capacitor Question
List,
OK everybody, let’s not get our pacemakers wound up<G>
The problem. (Long Intro)
I have about 15 pieces or so of older HP test equipment.
3586B, 5370B, 5335A to name a few. Because of their age of 20+ years a
few have failed and need repair. I
have decided to go on a wholesale electrolytic capacitor replacement on
all of
them. (Mouser will be able to declare an extra dividend)
For all the *standard* types I’ve chosen mostly Panasonic
105C 10,000 hour caps. So far, so good.
Now I come to the issue of the wet-slug tantalums that were
used. At the time of manufacture, these
were the best and most expensive low voltage electrolytics available.
The question is: can one replace the tantalums with the high
grade (105C) Panasonic or Nichicon capacitors with an equal or higher
capacitance value?
Even using the *tear drop* new replacements one is looking
at very heavy $$$.
Regards,
Perrier

Take a look at the Aluminum Organic Polymer Electrolytics.
Available in 105 °C and 125 °C. They have very low ESRs. In the milliohms.
