Besides even the shortest over-voltage incidents, Tantalums also don't like high current pulses. Low-ESR power sources with quick ramp ups are a no-no.
- xondono 8y agoYes, I read a lot about tantalums and their failure modes some years ago because we wanted to set some kind of use policy for our own products. After a lot of research and testing we ended up forbidding the use of tantalums in our designs and taking the cost hit whenever density was an issue. It’s a drastic measure but I think it was the right call, our products were a perfect mixture of all the things that tantalums don’t support well.
