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

Well, it appears to be metallized polyester film, but the part number and geometry seem to imply that it may be a custom part. I would guess it is rated for 1000V, but the capacitance must be more than 3.3nF.
Are you sure it's dead?

It's 3.3 something, probably rated at 1000V.

The "K" could be the tolerance of the value. K = 10%.

Or the K could be 1000's picofarads but as someone said above, 3300pf or 3.3nF seems a bit low for it's size.

Could be 3.3μF 1000V. The "MWR" will probably the manufacturers product range.
