Most likely polyester, since every other TRW X6XX series I've seen uses that material (X663 is a common metallized film polyester). X3XX capacitors are polypropylene. American Shizuki ate TRW capacitors a long time ago, but some of their offerings use a similar numbering scheme.

lighting fast repsond. thanks for your help !🙂
so how good are these X6 series capacitors? couldn't find its datasheet, are they good on the digital circuits especially on s/pdif input?

Do you have the dimensions of these capacitors?
Polypropylene are bigger than polyester (mylar) because of the lower dielectric constant of polypropylene.

Why any curiosity whatsoever about such inconsequential caps, when much better are available without much effort? General purpose polyester caps are not exactly thin on the ground...Polypropylene caps (much better) aren't exactly hard to find, either.
Edit - If you want, polycarbonate caps can be small (as small as polyester), but with better characteristics than polyester, and still not hard to find for those willing to do a little work.

More than likely Metalized Polyester - ran a quick design and polyester & foil won't fit in the given size.
Not necessarily - DK of BOPP is higher but volts/um is higher - so depending on the actual design of the capacitor they can be smaller
Really? How can polycarbonate be smaller than polyester when the DK is higher and polyester is available in thinner material that polycarbonate ever was? Polyester has an inherent higher voltage withstand that polycarbonate, therefore, in DC applications thinner dielectric can be used.
