Bulging, Leakage, and Short Circuits in Capacitors
Capacitors are essential components in electronic systems. They are widely used in PCB assemblies, household appliances, industrial control equipment, and new energy products, where they support filtering, coupling, voltage stabilization, and energy storage. But in real-world use, capacitor failures are common. Among all failure modes, bulging, leakage, and short circuits are the three problems seen most often. In mild cases, a failed capacitor may only cause unstable performance or reduced efficiency. In more serious cases, it can damage the PCB, destroy surrounding components, or even create a fire risk. Many…
