Resistor Color Codes & Primer Common Resistor To determine the value of a given resistor look for the gold or silver tolorance band and rotate the resistor as in the photo above.(Tolerance band to the right). Look at the 1st color band and determine its color. This maybe difficult on small or oddly colored resistors. Now look at the chart and match the "1st & 2nd color band" color to the "Digit it represents". Write this number down. Now look at the 2nd color band and match that color to the same chart. Write this number next to the 1st Digit. The Last color band is the number you will multiply the result by. Match the 3rd color band with the chart under multiplier. This is the number you will mulitple the other 2 numbers by. Write it next to the other 2 numbers with a multiplication sign before it. Example : 2 2 x 1,000. To pull it all together now, simply multiply the first 2 numbers (1st number in the tens column and 2nd in the ones column) by the Multiplier. Example: First color is red which is 2 Second color is black which is 0 third color is yellow which is 10,000 Torerance is silver which is 10% FAQ Just a few common questions to help you out. 1) Which side of the resistor do I read from? The Gold or Silver band is always set to the right, then you read from left to right. Sometimes there will be no tolerance band -- Simply find the side that has a band closest to a lead and make that the first band. 2) How do I remember this sequence of colors? Remember the color codes with this sentence: Big Brown Rabbits Often Yield Great Big Vocal Groans When Gingerly Slapped. Resistor Color Code Chart 1st. & 2nd Color Band Digit it Represents -----Multiplier----- BLACK 0 X1 BROWN 1 X10 RED 2 X100 ORANGE 3 X1,000 or 1K YELLOW 4 X10,000 or 10K GREEN 5 X100,000 or 100K BLUE 6 X1,000,000 or 1M VIOLET 7 Silver is divide by 100 GRAY 8 Gold is divide by 10 WHITE 9 Tolerances Gold= 5% Silver=10% None=20% Page 1
