Resistor color code calculator

 

This resistor color code calculator will help you determine the value of axial resistors marked with color bands. It can be used for 3, 4, 5 and 6 band resistors. You can select the colors of the corresponding bands by clicking on them in the table. The resistor will visually show your band color choices and display the value of the resistor above. If the resistance value is part of a standard E-series value, this will be shown in brackets after the resistance value. How to use the color code calculator Select the amount of bands of the resistor on the top-left Choose the colors of the bands by clicking on the corresponding box in the chart The corresponding ohmic value and tolerance of the resistor is shown Bands: 3 4 5 6 10k&#8486 ±5% 1st digit 2nd digit 3rd digit multiply tolerance TCR(ppm/K) Bad Black 0 0 0 1 1% (F) 100 Beer Brown 1 1 1 10 2% (G) 50 Rots Red 2 2 2 100 15 Our Orange 3 3 3 1K 25 Young Yellow 4 4 4 10K Guts Green 5 5 5 100K 0.5% (D) But Blue 6 6 6 1M 0.25% (C) 10 Vodka Violet 7 7 7 10M 0.1% (B) 5 Goes Gray 8 8 8 100M 0.05% (A) Well White 9 9 9 1G Get Gold 0.1 5% (J) Some Silver 0.01 10% (K) Now None 20% (M) Special cases 6 band resistors In the case of 6 band resistors, this calculator assumes the 6th band is used to indicate the thermal coefficient. In some rare cases the 6th band can also indicate the reliability of the resistor. For more information visit the main page on the resistor color code.
