SMD Resistor Code Calculator

This simple and accurate calculator for your iPhone or iPad, will help you determine the value of any SMD resistor. To get started, input the 3 or 4 digit code and hit the “Calculate” button.

How to calculate the value of an SMD resistor.
-Standard 3 or 4 digit markings that can include “R” to indicate a decimal point or “M” to indicate a decimal point for milliohms (Current sensing SMDs)
Examples: 330 3R3 4703

-EIA-96 1% markings with a number in the range 01 to 96, followed by a letter
Examples: 22A 68C 02F

-2, 5, and 10% markings with a letter, followed by a numbers in the range 01 to 60
Examples: A22 C58 F59
