Resistors Colour Code Values

The third band indicates the number of zeros. As i said some resistors have the fourth band on them.

The second band gives the second digit.

Resistors colour code values. Then value of resistor is 56 100 5600w ie. The colour code used to denote the tolerance rating of a resistor is given as. Brown 1 red 2 gold 5 silver 10 if resistor has no fourth tolerance band then the default tolerance would be at 20.

And the last color. In the example on the left these bands are green blue red and gold. For example a 390 resistor with a tolerance of 10 will have a value within 10 of 390 between 390 39 351 and 390 39 429 39 is 10 of 390.

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

Resistor values are usually shown using coloured bands each colour represents a number as shown in the table. Standard resistor values and color components and wires are coded with colors to identify their value and function. The colors brown red green blue and violet are used as tolerance codes on 5 band resistors only.

And the third band is a multiplier. Tolerance is the precision of the resistor and it is given as a percentage. Most resistors have 4 bands.

Enter the value select the multiplier w k or m the desired precision and hit display resistor or enter. To use this tool simply click on a particular color and number and watch how the actual bands on the resistor illustration change. Try out our resistor color code calculator in our tools section.

You can also type in resistor values in shorthand notation like 1k5 4m7 or 100r. The first two bands of resistor show the resistance value of the resistor. The four band color code is the most common variation.

Our resistor color code calculator is a handy tool for reading carbon composition resistors whether its a 4 band 5 band or 6 band type. The resistor color code calculator decodes and identifies a value and tolerance of 4 band wire wound resistors. The first band gives the first digit.

If you want to find out the color bands for a value use the tool on the left. If the colored bands on the resistor are green blue and red.
