 Color code

 

 
Resistor color code: As usual a resistor is marked by four or five ring strips. Since you can find out the value of the resistors at any installation of this one on a printed-circuit-board. Read value of the resistor from the end with a narrow strip in Ohms. Read a wide strip the last. Table 1 shows the decoding of the color marks for resistors. Up to multiplier marks are given in Ohms.

Capacitor color code Recently capacitors as well as resistors have color marks. However different types of capacitors can have different color strips or points at the body. Figure 1 shows examples of color marks for several types of modern capacitors.

 

 

Capacity is specified by two first colors (strip or points) in pF. After that the multiplier shows value of the capacitor. Tolerance, working voltage and also can be specified if it is necessary. Table 2 shows capacitor color marks. Table 3 shows lighting calculator for capacitors
