Resistor Values And Colours

Resistor values are often indicated with color codes. A 6 band resistor is like a 5 band resistor but includes a temperature coefficient band the 6th band.

Resistor values and colours. How to read color codes from resistors. Three of the bands tell you the nominal value which means the value the resistor was designed to have. The resistor color code is a long standing standard in both the electronics and electrical industries indicating the value of resistance of a resistor.

If you want to find out the color bands for a value use the tool on the left. Resistance is measured in ohms and there is a foundation for it called ohms law. Standard resistors have four color bands.

Practically all leaded resistors with a power rating up to one watt are marked with color bands. The fourth band tells you the tolerance of the resistor which indicates how far off the nominal value the actual resistance could be. Or there are much resistor calculators that you can use.

The coding is defined in the international standard iec 60062. Color bands are used because they can be easily and cheaply printed on a small electronic component. More online conversion calculators at digi key.

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. You can also type in resistor values in shorthand notation like 1k5 4m7 or 100r. In resistor color codes each color shows a specific value.

Brown 1 red 2 gold 5 silver 10 if resistor has no fourth tolerance band then the default tolerance would be at 20. In case of 3 band and 4 band resistors the first two color bands are showing the significant figures and their values while in 5 band and 6 band resistors the 1 st 2 nd and 3 rd color bands are showing the significant figures and related values. Every color is different number and you can remember these numbers or you can just use the table on next step.

Its for the lazi. The resistor color code calculator decodes and identifies a value and tolerance of 4 band wire wound resistors. The value of the resistor is marked on the body using colors.

A 5 band resistor is more precise compared to a 4 band type because of the inclusion of a third significant digit. Resistor band colors as shown above a carbon composition resistor can have 4 to 6 bands. The colour code used to denote the tolerance rating of a resistor is given as.
