# Resistor Color Codes

__Contents__## Four-band resistor color codes

(PDF file for 4-band color codes)**Yellow, Green, Orange, Silver**

Yellow and green represent 4 and 5, respectively. Those consist of the first and second digits, so it will be 45. The third band is orange. As a multiplier, it is × 1000, so you will calculate 45 × 1000; therefore, the resistance is 45,000 Ω. The forth band, silver, represents the tolerance, so the final expression of the resistance is

__45,000 ± 10% Ω__.

## Five-band resistor color codes

(PDF file for 5-band color codes)**Yellow, White, Yellow, Brown, Gold**

Yellow, white and yellow represent 4, 9 and 4, respectively. Those consist of the first, second and third digits, so it will be 494. The forth band is brown. As a multiplier, it is × 10, so you will calculate 494 × 10; therefore, the resistance is 4,940 Ω. The fifth band, gold, represents the tolerance, so the final expression of the resistance is

__4,940 ± 5% Ω__.

## Six-band resistor color codes

(PDF file for 6-band color codes)**Violet, Grey, Green, Red, Silver, Brown**

Violet, grey and green represent 7, 8 and 5, respectively. Those consist of the first, second and third digits, so it will be 785. The forth band is red. As a multiplier, it is × 100, so you will calculate 785 × 100; therefore, the resistance is 78,500 Ω. The fifth band, silver, represents the tolerance, 10%. The sixth band is the temperature coefficient of the resistor. Brown represents 100ppm/K. Namely, the final expression of the resistance is

__78,500 ± 10% Ω with Temp. Coeff. 100 ppm/K__.
