[sci.electronics] Unknown Component ?

Hello,
Does anyone happen to know what is a black disk that is inside a PC
switching power supply. The part has codes UEI and SP010 , I guess
that UEI is a manufacturer code and SP010 ( or SPO1O ) is the part
code.
All energy that goes into the power supply goes through that disk, I
think it is a PTC and it has something to do with overload protection.
I would appreciate all information about this one, especially
operating values and possible replacement parts would be nice.
