Hi all I wonder if I could help with the number of this component of a power of 60w. I was burned and can not see that number had, thank you very much!


 





It looks like either a ceramic disk capacitor, or a MOV.

If you can get a better picture of the symbol underneath it, I could tell you definitively what it is.
 
That would be an NTC (negative temperature coefficient) thermistor. Its a cheap way to limit inrush current. It probably blew for a reason i.e. a short somewhere else. You can select a value yourself if you know the typical mains operating current of your supply, but I would strongly suggest you find out why it burned first.

In a pinch, you can just short them out to bypass them. But that's bad if there's a fault elsewhere. At least it'll set fire to the fault - making it more visible :)
 
Thanks cyparagon the diode bridge its for 8 Amp could Putin the thermistor 8Amp
the lightning stalker the fuse is good :$
 
Okay, interesting. Well you can get NTC
thermistors out of old TVs and computer
power supplies. Find one with similar
specs. Or if you look very carefully, you
might find a piece that has some numbers on
it.
 
the lightning stalker there is the problem which are not specifications. Any numbers not seen that part was burned
