Hi
If we ignore the discussion about tantalums and dv/dt susceptibility, and focus on endurance. I have looked at different caps
Goes into FIT numbers in this page:
Stating a FIT of 5, which is good
Another one from Nichecon:
States endurance of 2000 hours at 85 degrees dropping 10% rated capacitance. But, will this curve stay one the same trend, so about 20% rated capacitance reduction at 4000 hours? (seems to me this is a very bad cap and can be used for next to nothing)
Anyone has experience of tantalums and capacitance versus lifetime in general?
Thanks
Klaus
