Electrical overvoltage, inadequate heat dissipation, and poor solder connections are other common causes of burning ceramic capacitors.
While it is rare, capacitors can potentially cause a fire if they fail catastrophically. Factors such as overvoltage, internal faults, or high temperatures can lead to thermal runaway, resulting in the release of flammable materials or ignition of nearby components.
Moreover, the capacitor lifetime depends directly on the operating temperature hence an overheating will lead to a faster aging. The main reason for a burning or even exploding capacitor bank is the liquid-filled capacitors, or the plastic parts that are combustible.
