Can anyone help me to identify the SMD capacitor in this photo? (at least I think it's a capacitor!)

\$\begingroup\$ Since there are no values present, the only real way to know the value would be to desolder it. If it is a capacitor, it is most likely a tantalum capacitor. It looks like it could also be an unusually, shaped diode. \$\endgroup\$– AzsgyMar 19, 2017 at 19:58

\$\begingroup\$ Maybe a photo with more of the board? There might be a marking that could indicate whether it is a capacitor or a diode (or something else.) \$\endgroup\$– JREMar 19, 2017 at 20:23

It's SMD diode - probably 1N4148/CD4148 (or similar small signal diode) in 0805 package (by the looks of it).

That device doesn't have any markings to tell its value.
The one-sided stripe might indicate it's a polarized device – maybe a diode?

Being black with a stripe near one end hints that this is not a capacitor at all. Such stripes usually show polarity. While some capacitors do have polarity, this doesn't look like the right kind of package for that.
It might be a diode, but since it has no other marking, you can't be sure other than by measuring it. Seeing some context around this part may also help.
