Can anyone help me on how to do a derating analysis for all the tantalum capacitors in an existing circuit?
Voltage, current, temperature? where would I look at the values I needed. Thank you.
 

See the attached article. Also, AVX has software on their web page to automate some of the calculations.

Go to tab marked "Spice models / software" then "select-a-cap 6.1"

It's according to your reliability requirement.As usual,one third of voltage,fifty percentage of capacitor.
