It seems that I will have to look at this. Should I expect those spikes at somewhat stable pattern or totally random? > Electrolytic caps should always be used at 90% of rated voltage or even > higher., a 16 volt cap used in a 3.3 volt circuit has a failure time > generally under a year.

When choosing caps for rectifiers I did choose such a voltage to have extra margin. It just felt better. Now it turns out that it was bad and unjustified choice. I will rephrase my original question - can anyone suggest ANY place where I can get a 8i20 drive? Today I discovered that store.mesanet.com is also out of stock on this item. Even if I fix that Yaskawa for now, I would like to have one spare 8i20 under my pillow.
