    is a 330m ohm resistor the same as a .33 ohm resistor?

    If you really mean 33 milliOhms (small m) then yes it is, although that's a very small value. If you mean 33 MegaOhms (big M) then no it isn't.

    its for a cooling fan mod that mini use, the mini forum say you need a .33ohm 100w power resistor to slow the fan speed this is the one i found on RS site

    That looks to be correct.

    For reference:

    0.1 ohm = 100 milliohms
    0.01 = 10 milliohms
    0.001 = 1 milliohm

    From long and bitter experience RS, Farnell &c sometimes get confused themselves about the difference between mR and MR - check it with a multimeter before you use it!

    RS technical emailed me to say that this manufacturer uses R as a decimal point so R33 becomes .33 ohm ,and 33R 33 ohm so all is well

    any electronic guys on here

    The BS 1852 Letter Coding for Resistors

    0.47 = R47 or 0R47
    1.0 = 1R0
    4.7 = 4R7
    47 = 47R
    470 = 470R or 0K47
    1.0K = 1K0
    4.7K = 4K7
    47K = 47K
    470K = 470K or 0M47
    1M = 1M0

    Where is the Ohm symbol.

    thanks for that ,so all seems ok,
    cheers
