How do I read a 4-band resistor?

The first two bands represent the first two digits of the resistance value. The third band is the multiplier (number of zeros). The fourth band indicates the tolerance (accuracy).

What is the difference between 4, 5, and 6 band resistors?

4-band resistors are the most common with 2 significant digits. 5-band resistors offer higher precision with 3 significant digits. 6-band resistors include a temperature coefficient band indicating how resistance changes with temperature.

What does the gold or silver band mean?

Gold and silver are typically used for tolerance (Gold = ±5%, Silver = ±10%) or as fractional multipliers (Gold = 0.1, Silver = 0.01) in the 3rd or 4th position.

Which end do I start reading from?

Start reading from the end that has bands closer together. The tolerance band (often Gold or Silver) is usually separated by a larger gap at the other end.

What is a Resistor Color Code Decoder?

A Resistor Color Code Decoder is a tool used to determine the resistance value, tolerance, and temperature coefficient of a resistor based on the colored bands printed on its body. These bands follow an international standard (IEC 60062) to indicate values where numbers cannot be printed clearly.
