Resistor Color Code Reference

Calculated Value

1.02 kΩ ±1%

Resistance: 1,020 Ω (1.02 kΩ)

Tolerance: 1% (Actual range: 1,010 Ω - 1,030 Ω)

Tolerance indicates the precision of the resistor. 1% tolerance means the actual resistance can be up to 1% higher or lower than the calculated value.

Understanding Resistor Color Codes

Resistor color codes are a standard method for identifying the resistance value of resistors. The 5-band resistor color code provides more precise values compared to the 4-band system. Each color represents a specific digit, multiplier, or tolerance value.

To read a 5-band resistor, start from the band closest to the end. The first three bands represent significant digits, the fourth band is the multiplier, and the fifth band indicates tolerance. Our calculator simplifies this process by providing instant calculations as you select each color band.

Resistors are fundamental components in electronic circuits, used to limit current flow, adjust signal levels, and divide voltages. Understanding how to read resistor values is essential for anyone working with electronics.
