Resistor color-coding scheme. Note that not all resistors have the same number of bands, so it is important to know the type of resistor at hand. If a resistor has only four bands, then it does not have the thir
It is a good practice to check the manufacturer’s documentation to be sure about the color coding system used. When in doubt, measure the resistance with a ohmmeter. In some cases this might even be the only way to figure out the resistance; for example when the color bands are burnt ...
Resistor Color Coding uses colored bands to quickly identify a resistors resistive value and its percentage of tolerance with the physical size of the resistor indicating its wattage rating. Generally, the resistance value, tolerance, and wattage rating are printed on the body of a resistor as nu...
ForSMD (Surface Mount Device) resistors, a numerical code is used, because the components are too small for color coding. SMD resistors are, just as for leaded resistors, primarily available in the preferred values. The size of the component (length and width) is standardized as well, and ...
