3 Band Resistor Color Code Calculator

Resistor color code calculator introduction

This is a tool to identify the resistance value of resistor.When the color on the resistor is selected, the resistance value of the resistor is displayed directly on the page.The tolerance, maximum and minimum values are also displayed. If 6 bands are selected, the temperature coefficient of resistance will be displayed.

How to Use the Resistor Color Code Calculator?

It's a very simple tool, Choose 3 band, 4 band, 5 band, or 6 band first, then select the corresponding color in several option boxes, and the resistance value will be displayed in the result bar immediately.

3 band Resistor Example

Key:

1: 1^st band      1^st numeral      Green = 5

2: 2^nd band      2^nd numeral      Red = 2

3: 3^rd band      Multiplier        Orange = x 10³

Result: Resistance 52KΩ, Tolerance ±20%
