How do you choose an aluminum electrolytic capacitor that’s suitable for your application?

When selecting aluminum electrolytic capacitors suitable for a particular application, one should not rely solely on the two parameters of capacitance and rated voltage. Instead, a comprehensive assessment should be made from multiple perspectives, including electrical characteristics, operating environment, expected lifespan, and actual installation conditions.

What could be the reason for the frequent burning out of capacitors?

Capacitors frequently burn out not because of a single factor alone, but rather as a result of the cumulative effect of multiple issues, including electrical stress, thermal stress, environmental conditions, and the degree of compatibility between the component selection and application requirements.
