:mrgreen: I have a small circular surface mount device with four pins connected to the four sides, north, south, east and west, as seen in the picture below. The device appears to be a FET and the only markings I see are E5 written on the top. It is part of an amplifier circuit but I don't think it is a transistor, since the board location is listed with a U instead of a Q. I've been trying for days to find the part number, with no success. I know it's not alot of information to go on, but if anyone can help me, it would be most appreciated.
