SMD Resistor Calculator

Calculate resistance values from SMD codes instantly

Enter 3 or 4 digits code from your SMD resistor.
Example: 103 = 10kΩ, 1002 = 10kΩ

SMD Code

Quick Guide

How to Read SMD Codes:

3-digit code: First two digits + multiplier
4-digit code: First three digits + multiplier

Examples:

Code: 103

10 × 10³ = 10kΩ

Code: 4702

470 × 10² = 47kΩ

Tips

Make sure the SMD component is a resistor
Clean the component surface for better readability
Use proper lighting for accurate code reading
