| #134: Teardown of failed power supply - bad capacitor This short video shows the teardown of a small, cheap linear power supply that failed after a few minutes of being plugged in for the first time. A small pop and hiss was heard, followed by some excessive heat. Luckily I was there to unplug it before it turned really ugly! The video shows opening the supply up, and looking at what failed - a bad capacitor, bulged and high ESR. https://youtu.be/NHVvkSbsr_Y |
