Unuse also can damage capacitors through oxidation. I've never seen a datasheet that said "make sure to stretch out your capacitor's legs at least once a year."

Unuse also can damage capacitors through oxidation. I've never seen a datasheet that said "make sure to stretch out your capacitor's legs at least once a year." Manufacturing errors can make capacitors die young, but even the most upstanding member of a capacitor tribe will one day kick the bucket through no fault of anyone's.
