Hi experts
I am having issues with my 100uF 20V 1206 tantalum capacitor for 12V input.
The ripple is lower, but close to the limit (said in the DS) [~150mA]
I am facing 20% failure.Most of the time, it explodes on the first power on.
Sadly I have a lot of PCB without any hope to change the PCB.
I haven't found much on the application of the tantalum.
I found that there is some condensation/crystallization time on the first
power up.
The article suggest to use 3xVin [Ohm] serial resistor.
I am not satisfied with this solution. I think it does not help on the
problem.
It only mitigates the problem and it will blow up in my customer hands.
Any experience or artical/book are welcome.
Thanks
Steve
