I have a USB hub specifically to fit in my car. It stopped working and i saw a burned J107 capacitor (see picture). It looks like it might have briefly caught fire as you can see the plastic under the capacitor deformed. It was hot enough that the other side (outside of the plastic box) also melted a little.
I'm curious - does anyone know what might cause a cap like this to catch on fire like that? Is it just a random manufacturing defect that can happen to anyone, or was there a design issue with the USB hub?
Also, does anyone know if these can burn hot enough to actually ignite a fire? I.e., was all that was ever going to happen was the melted case, or was there a possibility of something more serious?
The hub is plugged into the car 24/7, and likely it burned while unattended. So in case the manufacturer replaces it under warranty I wanted to know if there are any safety concerns with having something like this always plugged in?
