    What does "RV" stand for?

    What does "RV" on a pcb stand for? I want to say resistor voltage? I got a bunch of them on this Logitech mouse that's dead (no power, person plug wrong power brick into usb hub and fried everything that was plugged in.) When measured they only work one way and come out to 182k ohms.

    So what are they?

    One-way sounds like it's a rectifier. (AC-to-DC)

      Is this "RU"? Are both letters capitals? Is it printed with a backwards slant? I thought there was an "RU" that was an industry group, like "CE" for the consumer electronics industry association.

      I could be wrong though.

        That's the UL component symbol

          RV is usually board designator for Varistor

                They look like typical SMD caps, which are seen often on graphics cards.

                  the capacitor uses Cxx for the capacitor designator on this board. Rxx for the resistor, RV (Varistor for peotection) it is proably connected between Ground and the junction that needs to be protected.

                    Concur with budm, probably surge protection diodes. Another possibility might be temperature compensation thermistors.

                      If you are talking about the items in bottom right hand corner they are sm resisters
