出を発煙と誤認される不具合がある。Problems that the invention aims to solve: However, when reverse voltage, continuous overvoltage, or abnormal pulses are applied to electrolytic capacitors, an excessive current flows through the electrolyte, causing electrolysis and gas generation, and the electrolytic capacitor is damaged due to its equivalent resistance. In order to prevent the internal pressure of the electrolytic capacitor from rising due to the generation of heat and destroying it, the bottom of the case is made thinner to form a weak point as shown in Figure 3, and is equipped with an explosion-proof function to prevent explosion damage. Although it is prevented,
When gas or steam is ejected from the weak point as shown in FIG. 4, the electrolytic solution is ejected as gas or vapor, and the electrolytic solution is scattered around and contaminates other parts. There is also a problem where eruptions are mistaken for smoke.
