Resistor Band Explanation

3-Band Resistors:

• 1st Digit: Represents the first significant digit (the leftmost band).
• 2nd Digit: Represents the second significant digit.
• Multiplier: The factor by which the two-digit number is multiplied to determine the resistance value.
• Note: A default tolerance of ±20% is assumed.

4-Band Resistors:

• 1st Digit: The first significant digit (leftmost band).
• 2nd Digit: The second significant digit.
• Multiplier: The multiplier factor applied to the two-digit number.
• Tolerance: Indicates the percentage tolerance; located on the right side.

5-Band Resistors:

• 1st Digit: The first significant digit (leftmost band).
• 2nd Digit: The second significant digit.
• 3rd Digit: The third significant digit.
• Multiplier: The multiplier that scales the three-digit number.
• Tolerance: Specifies the resistor's tolerance; located on the right side.

6-Band Resistors:

• 1st Digit: The first significant digit (leftmost band).
• 2nd Digit: The second significant digit.
• 3rd Digit: The third significant digit.
• Multiplier: The multiplier factor applied to the three-digit number.
• Tolerance: Indicates the tolerance percentage; located on the right side.
• Temperature Coefficient: Represents the resistor’s temperature coefficient (ppm/K) and is not used in the resistance calculation.
