Tolerance Band Silver 10 % The resistor value is read from the left to right. If there is no tolerance band, then find the side that has Equation a band closest to a lead and make that the first band. 2 0 x 10,000 = 200,000 1,000 = 1K Resistor = 200 K with a + - 10 % Tolerance © Copyright 2006 Blue Point Engineering All Rights Reserved Page 1 Resistor Color Code 4 Band Quick Guide Resistance Notation Band 1 Band 2 Band 3 Tolerance .22 ohm R22 Red Red Silver S,G,R,B .27 ohm R27 Red Purple Silver S,G,R,B Color Value .33 ohm R33 Orange Orange Silver S,G,R,B Black 0 .39 ohm R39 Orange White Silver S,G,R,B Brown 1 .47 ohm R47 Yellow Purple Silver S,G,R,B Red 2 .56 ohm R56 Green Blue Silver S,G,R,B Orange 3 .68 ohm R68 Blue Gray Silver S,G,R,B Yellow 4 .82 ohm R82 Gray Red Silver S,G,R,B Green 5 1.0 ohm 1R0 Brown Black Gold S,G,R,B Blue 6 1.1 ohm 1R1 Brown Brown Gold S,G,R,B Violet 7 1.2 ohm 1R2 Brown Red Gold S,G,R,B
