Can anyone help me to identify the SMD capacitor in this photo? (at least I think it's a capacitor!)
It's SMD diode - probably 1N4148/CD4148 (or similar small signal diode) in 0805 package (by the looks of it).
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.
