What are Resistor Color Codes?

The electrical properties of resistors get marked with standardized colored bands through the resistor color code system.

The standardized band sequence provides immediate access to resistor characteristics, including ohm (Ω) resistance values, precision measurements, and thermal stability information.

4 Band vs 5 Band vs 6 Band Resistor Color Code Comparison & Reading Resistor Bands: A Quick Overview

A standard resistor comes with either four, five, or six colored bands. The resistor features bands which function for particular purposes:

• First & Second Bands: Represent the first two significant digits of the resistance value.
• Third Band: The third band indicates a power of 10 which needs to multiply the significant digits.
• Fourth Band: Represents the tolerance (precision) of the resistor.
• Fifth Band: In 5-band and 6-band resistors, adds an extra significant digit to enhance precision in these components.
• Sixth Band: The sixth band on 6-band resistors specifically shows the temperature coefficient of resistance (TCR).

How to Read the Resistor Bands Correctly

Reading resistor color bands can sometimes be confusing, especially for beginners. Follow these simple tips to read the bands correctly from left to right and get accurate results.

1. Select the Band Colors Carefully

Select the color for each resistor band in the calculator to instantly show the resistance value, including:

• Resistance value in ohms (Ω)
• Tolerance as a percentage (%)
• Temperature Coefficient (ppm/°C)

This feature helps you match the resistor color bands with the digital result, reducing mistakes and avoiding guesswork.

2. Identify the Tolerance Band Position

The tolerance band is always the last band on the resistor and is usually separated from the other bands by a wider gap. Gold and silver colors are never used for significant digits, so when you see them, you can confidently identify them as the tolerance band.

3. Look for a Wider Band

In many resistors, the tolerance band is printed wider than the other bands—often about 1.5 to 2 times wider—making it easier to identify the correct reading direction.

4. Check Manufacturer Documentation

For critical or precision applications, always refer to the manufacturer’s datasheet. It provides the most accurate and reliable resistor specifications.

5. Verify with a Multimeter

The most reliable way to confirm a resistor’s actual value is by measuring it with a multimeter. This is especially useful for old, damaged, or faded resistors.

Final Tip

By following these guidelines and using our Resistor Color Code Calculator, you can confidently and accurately identify any resistor value, ensuring your electronic circuits are built correctly and perform as intended.
