Can anyone identify these capacitors?

These are on a laptop motherboard but I can't get the schematic for it.

They are Fujitsu caps, first line is the series... I believe Fuijitsu sold the capacitor lines off to Nichicon now so series might have changed...

Second line is the value, using normal 3 digit capacitor codes (example 331 = 330pF & 391 = 390pF)

Third line is the voltage rating

That red mark looks like a polarizing indication. Do you think they might be electrolytics and perhaps a much higher value. Example: 331=330uF.

From what I've seen before the value is based on uF, not pF in this case.

331 is 330uF

TOK ;)

agreed, you are not likely to see 330pF electrolytic caps ;)

In addition, these are solid polymer capacitors, similar to a VERY low ESR electrolytic capacitor.

Check this thread for a recent query about almost exactly the same thing where you'll find some specific information.

These are in modern motherboards are called as solid state capacitors they are solid polymer capacitors. If you see some old motherboards you will find approx 12000uF to 20000 uF capacitance where used but instead today its just total around 1200uF to 1600 uF capacitance is used. So as steve said it has a very low ESR.
