5-Band Resistor Color Code

5-Band Resistor Color Code

Overview

  • A 5-band resistor is a passive electronic component primarily utilized to calculate resistance values with greater precision compared to 4-band resistors.

Band Structure

  • Resistors have distinct color bands that indicate their resistance values and tolerances. Each band holds specific significance:

    • 1st Band Value: Represents the first significant digit.

    • 2nd Band Value: Represents the second significant digit.

    • 3rd Band Value: Represents the third significant digit.

    • Multiplier: Indicates the factor by which to multiply the combined significant digits to arrive at the total resistance value.

    • Tolerances: Reflects the precision of the resistor in terms of allowable deviation in the resistance value.

    Tolerances

    • Tolerances illustrate the degree of accuracy in resistance value measured against the standard:
      | Color | Tolerance |
      |---------|--------------------|
      | Brown | ±1% |
      | Red | ±2% |
      | Green | ±0.5% |
      | Blue | ±0.25% |
      | Violet | ±0.10% |
      | Grey | ±0.05% |
      | Gold | ±10% |
      | Silver | ±20% |
      | No Band | ±20% |
