Hi. Hope you are all well.
I was really hoping someone could help me identify some components on a circuit board from an IP camera. Image attached.
Your assistance would be greatly appreciated.

 

1) 0-ohm resistor jumpers
2) possibly 15Ω resistor
3) SK36A 60V 3A Schottky rectifier
4) resistor or capacitor
5) capacitor
6) resistor or capacitor or ferrite bead inductor

 

My guesses:
1. - 0 ohm resistors, possible to set options with U5.
2. - missing D15 for reverse-polarity protection
3a. - RT1 resettable PTC fuse 150= 1.5A possibly
3b. - SK36A is a TVS diode for transient protection
4. - big MLCC capcitor
5. - small MLCC capacitor
6. - ferrite bead for filtering

 

Thank you @MrChips and @prairiemystic for your inputs. Much appreciated. Could number 2 possibly be a fuse of some kind? I am struggling to source a similar part when I search for a 15Ω resistor.

 

@Henkel,
If you don't recognize the components, how can you suspect one has failed?
What are the symptoms ?
Good luck..............

I have a second board like this that is blown. I am using this one as a reference. The big black burn mark and cracked components was a giveaway.

 

Thank you for your reply.
Is there any chance of a photo of the damaged board?
Did it self destruct or was it accidental?
Good luck........

Hi Twohats. Sure. Image attached. I accidentally, and stupidly put 240V through a 12V system. I have spent most of today going through all the components. Everything is shorting and I am not sure if I have multilayer connections that have been cooked. I was hoping the fuse took most of the hit with some minor collateral components going, but I think it is deeper than that.
