Resistor Color Code Calculator

🟢 About the Resistor Color Code Calculator

The Resistor Color Code Calculator is a powerful and easy-to-use tool that helps you quickly identify resistor values based on their colored bands. Whether you’re working with 4-band, 5-band, or 6-band resistors, this calculator provides instant results, including resistance value, tolerance, and temperature coefficient (for 6-band types).

🟡 How It Works

Resistors are marked with colored bands that indicate their resistance value and tolerance. This tool simplifies the decoding process by allowing you to select the color for each band and instantly displaying:

  • The resistance value in ohms (Ω), kilohms (kΩ), megohms (MΩ), or gigohms (GΩ)
  • The tolerance percentage (±%)
  • The temperature coefficient (for 6-band resistors)

No more manual calculations or confusing charts — just select the colors and get accurate results instantly.

🔵 Supported Resistor Types

  • 4-band resistors – Common in general-purpose electronics
  • 5-band resistors – Used for higher precision
  • 6-band resistors – Include temperature coefficient for precision in varying environments

🔍 Why Use This Tool?

  • ✔️ Fast and accurate resistance decoding
  • ✔️ Mobile-friendly and responsive design
  • ✔️ Useful for students, hobbyists, and professionals
  • ✔️ Supports tolerance and temperature coefficient analysis
