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


Thanks

47k. The number after the value (in ohms) is the number of zeroes
that follow.

47000

The 3 is the number of zeros, 4.7K would be 4D73 "D" for the decimal
point....

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
value.

Peter,
47K is a pretty common pot.

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......

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.

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.

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