Subject: X5R capacitor burn-in at +125degC/168hrs
The X5R ceramic capacitor operating range is -55 to +85 degC. This relates to the capacitance value, as certain capacitance range (+/-15%)is guaranteed within the above temperature limits.
Would anyone be able to advise what happens if you burn-in the X5R capacitor at temperatures above +85degC, for example at +125degC for 168 hours - would there be any permanent damage (and which failure modes) or capacitor would recover once it cools down with no impact on reliability?
