    I have a broken pot with 473 written on one side - is this 4.7K or 47K
    ? I always forget. :)

    The 3 is the number of zeros, 4.7K would be 4D73 "D" for the decimal
  4. IF that is the value, then it is 47K - however, I don't think I've
    ever seen a pot of that value - pot values usually go 1, 2, 2.5, and
    5, followed by some number of zeros.

    I suspect that 473 is (part of) the maker's model number, not the

    47K is a pretty common pot.
  6. 47 + 3 0=47000, or 47K

    Just to confuse things, the standard speed control pot for a curtis
    golf cart controller is 5K, I dont think the K matters... you could use
    a 10K or a 20K pot and it wold work fine. You used to be able to get 1
    meg pots back in the tube TV days.... that might make the controller a
    little squirrly and noisy..... like touching the tip of a hi
    impedance guitar cord......

    w user info:
    Really? I don't think I've ever seen one. If his _is_ 47k and it's
    a 10% pot, then its lowest resistance, end-to-end (neglecting
    terminal resistance) will be 42300 ohms, and its highest resistance
    will be 51700 ohms.

    More than likely it's a 50k pot with an element tolerance of 10% and
    terminal resistances, on both ends, of 100 ohms or less.

  11. Hmmm - I see pots with various odd values listed on the Maplin site,
    but almost all pots listed in the Newark catalog have values in the 1,
    2 (or 2.5), 5 sequence. Those odd values must be a British thing.

    If the original poster does have a 47K pot, I'm sure he can safely
    replace it with 50K, which may be more readily available.

    Special order at Newark, but available.

    subj: 47x10 = 47K Ohms

    I've not seen any marked that way, more likely 472 or 4K7
