And the winner is... SMD Resistor Code Calculator!

12/23/2025

The most popular calculator on T&M Atlantic is the SMD Resistor Code Calculator, widely used by engineers and technicians for fast and accurate component identification.

SMD Resistor Code Calculator allows you to determine resistance by the SMD (surface mount device) resistor markings found on the device and to determine SMD resistor markings by resistance. It displays rated resistance and resistor tolerance.

This tool supports 3-digit code, 4-digit code and EIA-96 code.
