Resistor Color Code Chart

If you're working with electronic circuits, understanding resistor values and their corresponding color codes is essential. At BizzLibrary.com, we offer a comprehensive Resistor Color Code Chart that makes it easy to determine the value of a resistor at a glance. Whether you're an electronics student, a hobbyist, or a professional, this chart is an invaluable tool for your work.

What is the Resistor Color Code?

Resistors are passive components that oppose the flow of current in an electrical circuit. Their value is measured in Ohms (Ω) and can range from a few ohms to several megaohms. The resistance value of a resistor is indicated by a series of color bands applied to the component's body. Each color represents a number, and the combination of colors indicates the resistance value, tolerance, and temperature coefficient.

How to Read the Resistor Color Code Chart

Our Resistor Color Code Chart is simple to use. Based on the color bands on the resistor, you can read the value, tolerance, and temperature coefficient of the component. Here's a breakdown of how to interpret each band:

• Band 1 (1st Significant Digit): The first color band represents the first significant digit of the resistance value. For example, if the first band is brown, the first digit would be 1.
• Band 2 (2nd Significant Digit): The second color band represents the second significant digit of the resistance value. For example, if the second band is green, the second digit would be 5.
• Band 3 (Multiplier): The third color band represents the multiplier or the number of zeros to be added to the first two digits to get the complete value. For example, if the third band is red, the multiplier would be 2 (i.e., 10^2 or 100).
• Band 4 (Tolerance): The fourth color band represents the tolerance or the allowable deviation from the rated resistance value. For example, if the fourth band is gold, the tolerance would be ±5%.
• Band 5 (Temperature Coefficient): Some resistors may have a fifth band that indicates the temperature coefficient of the component (i.e., its change in resistance with temperature variation). This band is usually located close to one end of the resistor and is often blue.
