    Im stumped on two capacitors I can't quite figure out their size.
    They are small capacitors
    One side has
    the other side has
    Is this one 470 micro F

    The other one has;
    the other side has
    And is this one 235 micro F

  2. That's an odd value, 235uF...not impossible, though.

    How is it shaped? 4R7 means a 4.7 ohm resistor, usually.

  3. I might guess that it is 47 pF (4, 7, and no zeros) - but I might vary
    my guess based on the size of the capacitor.
    As another poster suggests, 4R7 suggests a 4.7 ohm resistor.

    235 doesn't seem to be a value - "23" isn't a standard value, but "22"
    is - 225 would be 2.2 uF

    You will only rarely see capacitors or resistors with values specified
    to three digits.

    They are both a sort of gold/orange. Both are small perhaps a little smaller
    than a grain of rice. The 4R7 is a little more square than the 470. Perhaps
    I will try putting the one that you both think is a resister on the ohm
    meter and see if it reads the right amount. The reason I thought they were
    capacitors was that they look like the same kind of packageing and color as
    other capacitors I have.
