Need help finding capacitor

[abicash]

Hi
I am repairing a psu, and there is a capacitor in the output stage which I am trying to find.
Written over it is
IC 3.3K1000MWR
Googling,i found its from Illinois capacitors.but I am not able to find similar part no in their list.
Can someone explain what the nomenclature means and which is the exact part no?
Any help appreciated.
Thanks

I would presume 3300pF?, but what is it in, and what is it doing?.

Hi Nigel
That is what i assumed but looking at the product list of Illinois capacitors, i cannot find this particular capacitor.
This is across IGBT's.
I am attaching the photograph of this capacitor.
