If you want to know why electrolytic capacitors explode, you must first know what electrolytic capacitors are. An electrolytic capacitor is a type of capacitor that utilizes a metal foil as the positive electrode, such as aluminum or tantalum.
heat
Capacitors are also rated for "ripple current" and exceeding the ripple current rating will increase internal heating and reduce lifetime. This is an additive effect with temperature. eg If two capacitors are operating at 50C then the one with a larger ripple current will have a shorter lifetime. Formulae are available to allow ripple current

What would cause capacitor to explode? | Finddiffer
The main two reasons that would cause a capacitor to explode is Reverse polarity voltage and Over-voltage (exceeding the voltage as little as 1 – 1.5 volts could result in an explosion). Electrolytic capacitors are more susceptible to explode as opposed to other types of capacitors.
What is the Standard Lead Spacing for Capacitors?
Question 1: Is there a reason why some capacitors have three leads? Answer: A capacitor with three leads is especially common when its capacitance can be adjusted. By adjusting the contact between the wiper and the main capacitor plates, a variable capacitance is achieved by adding or subtracting leads from the main capacitor.
What can make a ceramic capacitor blow?
Both of these the initial failure is not the cause of the visible damage. The fault causes the capacitor to become a conductor and the resuting high current from the power supply causes the sudden obvious failure. The capacitor stops being an insulator and instead becomes a sort of resistor. Power dissipation in that resistor is the actual cause.

6 FAQs about [What is the reason for the capacitor to explode ]
What causes a capacitor to explode?
The next factor that might cause a capacitor to explode is Over voltage. A capacitor is designed to hold a certain amount of capacitance as well as withstand certain amounts of voltages and currents. The voltage of a capacitor is usually displayed on the outside of its packaging.
Can electrolytic capacitors explode?
Electrolytic capacitors do not store very well. Their voltage rating drastically reduces the longer they are stored for as their internal chemistry deteriorates. This could cause a capacitor to explode as it might display a certain voltage, but its actual voltage has reduced.
Are all types of capacitors prone to explosions?
Not all types of capacitors are prone to explosions. However, certain types, such as electrolytic capacitors, are more susceptible due to their construction and materials used. Please click here to learn about the reasons for the explosion of electrolytic capacitors.
How does a capacitor work?
A capacitor is designed to hold a certain amount of capacitance as well as withstand certain amounts of voltages and currents. The voltage of a capacitor is usually displayed on the outside of its packaging. Exceeding these voltages can cause the dielectric to fail which results in large currents flowing.
