RESISTOR COLOR CODE
Token resistor color coding system
Token resistor color coding system applies to carbon film, metal oxide film, fusible, precision metal film, and wirewound (cylindrical with enlarged ends) of the axial lead type. This system is employed for resistors when the surface area is not sufficient to print the resistance value for the past time. At present, Token resistor color coding system is applying for automatization. The first three bands closest to one end of the resistor are used to determine the resistance. The fourth band represents the tolerance of the resistor. Additional information can be obtained from the first band. Generally, If an additional fifth band is black, the resistor is wirewound resistor. If an additional fifth band is white, the resistor is fusible resistor. If only one black band in the center, the resistor is called zero ohm resistor. The colors of the first two bands represent the numerical value of the resistor. The third band represents the power-of-10 multiplier.
How to read the resistor code
First find the tolerance band, it will typically be gold (5%) and sometimes silver (10%).
![]() If the 'multiplier' band is Gold move the decimal point one to the left.
