Cause of metallization capacitor explosion
Dec 23, 2018

1.If the shell (outer seal) layer is only cracked, it indicates that the voltage fluctuation of the external power supply network is caused by the voltage tolerance problem.

2. If metal molten slurry (generally tin or zinc) flows out of the gold-spraying layer at the lead end of the metallized capacitor, the main problem is that the capacitor cannot withstand the change of ripple current, the capacitor process quality is poor, and the capacitor with a wide range of high-frequency short-circuit loss Angle is likely to cause similar problems.

3. If the ambient temperature of the capacitor is too high, it will generally cause the breakdown of the capacitor, and the breakdown capacitor will fail. It won't explode.
