Why do caps blow? ie, swell | All About Circuits
Yup, as Dr.killjoy said, the heat tends to dry out the electrolyte and the increased resistance causes them to bloat and change its capacitance.
Does the ripple current specification in capacitors matter?
Does the ripple current specification in capacitors matter?
Yes! Too much ripple current leads to heat generated in the capacitor. When the heat generated by the ripple current exceeds the maximum …
