Are you confused by the numbers you see on SMD resistors? These 3 digits indicate their resistance value. These 3-digit SMD resistors are the most common in tiny electronic circuits, which are surface mount type of resistors.
How to Read 3-Digit SMD Resistor Codes
The black small square-shaped component with three digits. Yes, it is an SMD resistor. Traditional through-hole resistors use color codes to show the resistance value. An SMD resistor uses just 3- or 4-digit numbers. The 3-digit marking system is typically used on resistors with a 5% tolerance
- The First two digits represents the significant values.
- The Third digit is the multiplier. (The number of zeros to add to the end).
Do you want to check normal through hole resistor color code, resistance value or any other components related calculations the complete electronics calculators will solve the problem for searching every calculators individually.
How the 3-Digit Code Works
The first two digits indicate the resistance value and the third digit is its multiplier value. in an example, you see the SMD resistor with the numbering of “472” which means,
How to Use This Calculator
You can see the first digit, second digit, and multiplier numbers in the calculator. Just look at the SMD resistor to see which number is on the resistor and select the number, and do the same for the second and third numbers. After properly selecting 3 numbers, you can see the SMD resistor’s resistance value in the result section.
Common 3-Digit Resistor Codes
You can also change the unit of resistance to be displayed in here by selecting the unit from the drop down option. if the result showing large number in ohms, better to switch ohms to Kiloohms or mega ohm for better understanding.
