I have a blue ceramic disc capacitor and I'm trying to work out the values. On one side of the disc are the following characters, in approximately this pattern:

X 1400-
Y 1250-
E 222M

The other side has a bunch of logos and symbols which I can't make out. I imagine the capacitor is 22 nF, but I'm trying to work out the working voltage is.

That is a South Hongming 2200pF E-grade Y5V X1(400V)/Y1(250V) safety capacitor. The symbols are the numerous safety certifications the capacitor has.
