Hello,

I have a burned circuit and I don't know how to identify the smd components, the GH17M and the SS14 are not the problem but the burned SMD on the C5 emplacement is.

I think it is a capacitor but wich one with wich values...

I have wrote to the manufacturer but no luck

Does somebody recognize maybe this circuit or knows what could be the parts?

I appreciate you're help,

Bjorn.

 

The reference circuit for this regulator (GH17M) shows an electrolytic capacitor of 22uF for C5, the output capacitor, which looks to like a multilayer ceramic type on the image of your pcb but may be a tantalum type, it’s difficult to be sure because of the damage. Voltage rating of 6.3V would be appropriate.
A couple of questions come to mind :-
1. What damaged C5.
2. Is the regulator functioning.
Powering the regulator section using an adjustable bench power supply would be a useful way of testing the circuit.

 

Thank you Poyntat
