Hesener, you could just append the latest links to the first post in the thread, that usually works. I always check the first post in a GB thread before trawling the rest of the thread.

We need more measurements to be able to help.... You can remove the "cooked" caps and power the boards so measurements can be made.
I will do it today and will report. I still have the 6800 caps from GB. I only cange them because of footprint spacing.

Yes, just , but I did want to tell you that this is 'rock bottom'.

No. At 24V the regulator is not able to remove 'all' input voltage irregularities.

Hi Frans

He means his caps blew open and are dripping liquid.

The answer to that was the 'no'-part (e.g. It does not create 'dripping liquid'). And I do not know how to create 'dripping liquid', besides, mounting the caps polarity reversed, or using a to low a voltage rating, other than that only very bad luck will create two caps with the 'dripping liquid'-syndrome.

Did you check your caps voltage rating ?

No, they are the same (electrically), but differently packaged. I would recommend to use the 'FP', it is fully isolated.
