โ„น๏ธ About Resistor Color Code Decoder

The Resistor Color Code Decoder is an essential tool for identifying the value of through-hole resistors. Resistors use a series of colored bands to represent their resistance value (in Ohms), multiplier, and tolerance.

This tool supports:

  • 4-Band Resistors: The most common type. Two bands for value, one multiplier, and one tolerance band.
  • 5-Band Resistors: High-precision resistors with three bands for value, one multiplier, and one tolerance band.
  • 6-Band Resistors: Includes an additional band for the Temperature Coefficient (ppm/K).

๐Ÿ“– How to use Resistor Color Code Decoder

  1. 1. Select the number of bands on your resistor (4, 5, or 6).
  2. 2. Pick the color for each band starting from the left (the side with the bands closer together).
  3. 3. The tool will instantly calculate the resistance value, tolerance, and temperature coefficient if applicable.

โ“ Frequently Asked Questions

Which side do I start reading from?

Start from the end where the color bands are grouped more closely together. The last band (tolerance) is often slightly separated from the others.

What if my resistor has a gold or silver band in the middle?

Gold and silver in the 3rd or 4th position usually act as multipliers (0.1 and 0.01 respectively).
