Hi
The only thing I would add to that is: Get it from Mouser or Digi-Key. That way you have a pretty good chance of it being one that really came from the manufacturer you think it’s coming from. You also are a lot less likely to get one that has been on the shelf forever and ever. One really strange thing about Tantalum’s: They *like* bias and temperature. The time you are most likely to see high leakage is when they have been power off for a long time. That’s another reason to want a new one … Bob > On Jan 20, 2016, at 1:59 AM, Charles Steinmetz <csteinm...@yandex.com> wrote: > > david wrote: > >> It's a 2.2uF cap, with a 0.125" lead spacing, and I'm looking for 125dC temp >> rating.
