Marking system of Tokenchina - resistor color codes are applied to fixed resistors such as carbon film,
metal oxide film, fusible, precision, anti-surge, current sense, power, high voltage, and wirewound resistors of axial lead type.
In the past, this resistor codes are employed when the surface area is not sufficient to print the resistance value in digital.
At present, Tokenchina resistor 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 applied on the fifth 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.
The marking material of Tokenchina's color codes meets RoHS compliant with Pb-free.
- Marking are resistant to all normal industrial cleaning solvents suitable for printed circuits.
- Marking will not burn or emit incandescent particles under any condition of applied temperature or power overload.
