Resistor Colour Code Wattage

Generally on larger power resistors the resistor colour code systems is not required as the resistance value tolerance and even the power wattage rating are printed onto the actual body of the resistor instead of using the resistor colour code system. This tool is used to decode information for color banded axial lead resistors.

Resistor Color Code And Identification Charts Value Colour

By using the color code chart one finds that green stands for 5 and blue for 6.

Resistor colour code wattage. Brown is the multiplier 10 1 10 and gold is the tolerance 5. This chart shows you how you can read the resistor color bands. These resistors have two bands for the resistance value one multiplier and one tolerance band.

Resistor color coding color coding is a method used to indicate the resistive value tolerance and temperature coefficient of resistors with low wattage rating because of their small size. With that knowledge realize that on a four band resistor the third color will always be blue 106 or less and on a five band resistor. Select the number of bands then their colors to determine the value and tolerance of the resistors or view all resistors digi key has to offer.

The value is thus 56100 5600 w. In the example on the left these bands are green blue red and gold. If the 3rd band would be red instead of brown the multiplier would be 10 2 100.

Resistor color codes chart. Green and blue are the first significant digits 56. 56 x 10 560w.

The four band color code is the most common variation. Position the resistor with this band on the right side and again read your resistor from left to right. Generally on larger power resistors the resistor colour code systems is not required as the resistance value tolerance and even the power wattage rating are printed onto the actual body of the resistor instead of using the resistor colour code system.

In the case of 5 band and 6 band resistors the first three bands indicate the significant digits and the fourth band indicates the multiplier. In the case of a 3 or 4 band resistor the first two band indicate the significant digits and the third indicates the multiplier. 5 band resistor color code calculator.

Color bands are used because they can be easily and cheaply printed on a small electronic component. 4 band code 5 band code resistor color code guide 2 0 x10000 10 20 x 10000 200000 1000 1k resistor 200 k with a 10 tolerance first band second band multiplier band tolerance band equation the gold or silver band is always placed to the right. So for a 560 ohm 5 resistor the color stripes will be green blue brown and gold.

The resistor value is read from the left to right. Basic resistor values range from 01 ohm to 10 megaohms.
