    Hi all,

    I don't know much about electronics, read a few articles on capacitors, but the one I have seems to have different values on it. Could someone help me to ID it?

    many thanks,

    Hello
    It's not a capacitor it's a varistor for surge suppression.
    Thanks

    The designator on the board below the device is 'VDR3'
    VDR is 'Voltage Dependent Resistor', or to us techs, a 'Varistor', NOT a Capacitor.
    It might be easier to identify its value if you check data on varistors.

    I am trying to buy one of those online. got as far as figuring out s05k35 which are the first two lines on the varistor. what does 11 40 (the bottom line) stand for?

    why do you think its faulty ??

    when they fail its usually explosively obvious literally

    hi Davenn, that one is not faulty, but an identical one on the same board exploded - it got more voltage than it was designed for.

    I don't know for sure anymore, the new start-up Pacific Rim fly-by-night mfgrs seem to be coming up with their own marking system.
    Typically, I would consider it a Date Code. The '11' would be mfgr year 2011, and the '40' would be the 40th week of the manufacturing year.

    thanks a lot for the reply.

    I have seen a few example online where the year-week representation might be less likely (e.g. here and here) unless they are selling 27 years old components.

    I just want to establish if that is relevant for me when buying one, or I can just ignore those numbers?
