Help me find a capacitor
MonMotha:
I didn't say it was definitely used as a line filter, I said those kind of parts are often used as a line filter. There's no context, here, so who knows what it's used for.
Regardless, I can't think of an appropriate instance to do what you indicated (remove and short). I can think of many cases where doing such a thing to a component like this would be very bad. Replacing it with a standard film cap would also generally be a bad idea. X2 caps don't get spec'd "just because".
DaOld Man:
Its most likely a line filter.

--- Quote ---Class X is for applications where failure could not lead to electric shock (hot to neutral). Class X1 capacitors are intended to operate safely even in the presence of spikes on the mains supply of up to 4 kV (installation category 3 or overvoltage category 3 according to IEC60664), which are normally industrial supplies, but some standards call up class X1 capacitors if they are connected directly to the mains supply upstream of the equipment fuse, irrespective of the type of mains supply. Class X2 capacitors are intended to operate safely even in the presence of spikes on the mains supply of up to 2.5 kV (installation category 2 or overvoltage category 2 according to IEC60060), which are normally residential, commercial and light industrial supplies. X capacitors can be found from 0.001 uF to at least 10 uF and are only made in film.
