On this board, I'm trying to identify the burned component, which I believe might be a capacitor. When zooming in, I think I recognize "47" written on the first line, and maybe "16V" on the line below. This board is powered by a 15V power supply.

I don't know if it's a capacitor. It might be, because the empty space nearby (which was empty when disassembling) could have been a replacement for a non-SMD version of the capacitor, and it's labeled "C1".

I don't know what 47 means. Is it 47µF? Is it .47µF? Is it 47pF?

With only 2 numbers, I can't read it.

May you give me some hints please?

It was a 47uF 16V tantalum capacitor.

  • \$\begingroup\$ Thank you for your answer. May I ask you to confirm that when only two numbers are written, it means that this value is in µF ? \$\endgroup\$ – NEC Dec 20 '19 at 9:37

For the long story, here is what it was about : https://bricolage.ecarnot.net/robopong/ So sorry it's written in french, but the bottom of the page will make you understand. Thanks again, and have a nice day. Nicolas \$\endgroup\$ – NEC Jan 28 at 11:34
