• For resistor calculator, enter the colors on the resistor above.
• The last two bands that are on 4 and 5 colored resistors are MULTIPLIER and TOLERANCE
• If the resistor is 4 colored, leave the 3rd band and temperature coefficient empty.
• If the resistor is 5 colored, leave only the temperature coefficient empty.

### 4 BAND RESISTOR SAMPLES

4 Band Resistor Calculate

Coefficient = Violet (7), Green (5)Multiplier = Brown (1)Tolerance = Gold (%5)

Resistor Value = 75×101 = 750 Ohms

4 Band Resistor Calculate

Coefficient = Brown (1), Black (0)Multiplier = Brown (1)Tolerance = Silver (%10)

Resistor Value = 10×101 = 100 Ohms

4 Band Resistor Calculate

Coefficient = White (9), Brown (1)Multiplier = Yellow (4)   Tolerance = Gold (%5)

Resistor Value = 91×104 = 910 kOhms

4 Band Resistor Calculate

Coefficient = Brown (1), Grey (8)Multiplier = Red (2)Tolerance = Gold (%5)

Resistor Value = 18×102 = 1.8 kOhms

4 Band Resistor Calculate

Coefficient = Red (2), Red (2)Multiplier = Yellow (4)Tolerance = Gold (%5)

Resistor Value = 22×104 = 220 kOhms

### 5 BAND RESISTOR SAMPLES

5 Band Resistor Calculate

Coefficient = Brown (1), Black (0), Black (0)Multiplier = Brown (1)Tolerance = Brown (%1)

Resistor Value = 100×101 = 1 kOhms

5 Band Resistor Calculate

Coefficient = Orange (3), Orange (3), Red (2)Multiplier = Red (2)Tolerance = Brown (%1)

Resistor Value = 332×102 = 33.2 kOhms

5 Band Resistor Calculate

Coefficient = Blue (6), Grey (8), Brown (1)Multiplier = Orange (3)Tolerance = Brown (%1)

Resistor Value = 681×103 = 681 kOhms

### 6 BAND RESISTOR SAMPLE

6 Band Resistor Calculate

Coefficient = Brown (1), Black (0), Black (0)Multiplier = Silver (0.01)Tolerance = Red (%2)

ppm = Brown (100 ppm)

Resistor Value = 100×10-2 = 1 kOhms
