Hi,
I got this 2 components from a 12v 25A power supply. I don't know what it is.




This is something like a current sensing transformer, I don't know its just a guess.


And this was attached to one of the transistor on heat sink, maybe a temperature sensor? I can't find a datasheet for this.

 

The first item is a transformer (Probably high frequency.) or an inductor. Trace out the schematic of the power supply it was removed from showing where this item was in the schematic and we will probably be able to give a better answer. I think the second item is more likely to be a thermal fuse (105 Deg. C) than a temperature sensor.

Les.
