  1. Overheating and explosion risks: One of the most significant dangers of electrolytic capacitors is the risk of overheating and explosion. This can occur if the capacitor is subjected to excessive voltage or current, causing it to overheat and potentially rupture. The release of gas and electrolyte from the capacitor can lead to a violent explosion, posing a serious safety hazard.
  2. Leakage and corrosion risks: Another potential danger is the risk of leakage and corrosion. Over time, electrolytic capacitors can develop leaks, which can result in the release of corrosive electrolyte. This can damage surrounding components and circuitry, leading to malfunctions or even complete failure of the device.

It is important to regularly inspect electrolytic capacitors for signs of leakage and corrosion, and replace them if necessary to prevent any potential damage or safety risks.

Overheating and explosion risks

One of the potential dangers associated with electrolytic capacitors is the risk of overheating and explosion.
