For Silver, it is 10%, Black indicates 1% and 2% tolerance is indicated by Brown. In this case, it is Gold which indicates a 5% tolerance value. The last band in 4 and 5-bands resistors is the markings for tolerance value in the resistor.Next 3rd one is multiplier 0.1 ∴ look for color in chart having value 0.1, then it’s your 3rd color will be gold. The next 2nd digit is ‘ 0 ‘, ∴ look for color in chart having value 0, then it’s your 2nd color will be black. So for 1-ohm resistor, 1st digit is ‘ 1 ‘, ∴ look for colour in chart having value 1, then it’s 1st color will be brown.

Theoretically, the value of 1 Ω resistor is between 0.95 Ω to 1.05 Ωĭescription: From the chart we got the color code of resistor with respect to the decimal value of the respective band counted from left to right. The tolerance will be –> 5% of 1 –>0.05 Ω grey green grey gold black 8 | 5 | x0.001 | 5% | non-inductive => 0.4-band 100 ohm resistor color code is calculated as:.

brown black silver gold black 1 | 0 | x0.01 | 5% | non-inductive => 0.1 Ohm.One other thing I've seen is also pink as the 0.001 multiplier, in some other companies datasheet, just to give you an idea if you're picking your brain deciphering some odd looking resistor. I figure some other companies might also use this scheme for 'ultra' low value resistors (anything lower than 0.01 Ohm or requiring a further decimal in the tens of miliohms). The defining characteristic is a final black band, indicating non-inductive (and not a temperature coefficient marking, as these are 300ppm/K, a class that doesn't exist in the traditional marking scheme, black would otherwise be 100/200/250 ppm/K depending on who you ask). Now that datasheet says these should have a green colored body, and these are grey, but some show the Yageo ones in grey too, so whatever, even if they are clones, they follow this numbering scheme.

Our guess is that these are Yageo NKN series wire-wound non-inductive resistors (available E24 0.03-220 Ohm, 1-7W), 1W type. So after much searching and some great advice from I managed to find a datasheet with an updated/more detailed table of the resistor color code markings. May the wiseth shareth their wisdom with us mortals! To my mind one is brown, black, silver, gold, blackĪnd the other gray green silver gold black.

Any of you kind folks seen something like this before, and could maybe explain the code for this type of niche resistor? My guess is that these are some kind of fancy current sensing resistors, with super low resistances (the standard color code doesn't allow for anything lower than 0.01 Ohm).

Both test 0.0 or 0.1 on my multimeter, and both look brand spanking new, no burn marks, and the power supply works a treat. I am at a loss as to their values, as neither seem to follow the standard color code we all know and love. I was just disassembling an Asus 19V 4.74A laptop SMPS power brick, and came across these two resistors. The non-inductive resistors treated in this question use a unique color coding scheme which differs greatly from the standard code, and as this issue has never been raised on Stack Exchange or the internet at large, it is valuable to present an explanation of its recognition and interpretation, as it is otherwise almost impossible to find information about them. Here we identify the color code determining the values of non-inductive wire wound resistors, specifically Yageo's NKN series (but applicable to other manufacturers of this class), which are a unique and separate case recognizable by a final black stripe, NOT TO BE CONFUSED WITH CASES OF normal 3 or 4 BAND RESISTORS WITH AN ADDED TEMPERATURE COEFFICIENT BAND, which are then often wrongly interpreted/read as 4 or 5 band resistors respectively, as is the case in the answer of which my question was wrongly deemed a duplicate of!
