Tantalum capacitors break to form a short while essentially any other option breaks and becomes an open circuit. A short dumps a pile of current across the cap

Tantalum capacitors break to form a short while essentially any other option breaks and becomes an open circuit.
A short dumps a pile of current across the capacitor. an open circuit usually just means your circuit doesn't work well.
Don't use tantalum without a careful plan to deal with this issue... why are you forced to use them instead of a modern electrolytic?
- zwirbl 7y agoI am in the lucky position to develop the firmware for the device / not being the electronics guy The reason is a mismanaged project. Power budget on a CR2032 is tight and initially a supercap with much bigger capacity was planned. The company producing those went out of business and people were forced to somehow get it to market, working. We did, but now those new tantal cap problems arrived.
