SMD Resistor Code Reference

3-Digit Code (±5%)

First two digits = significant figures, third digit = multiplier (power of 10).

4-Digit Code (±1%)

First three digits = significant figures, fourth digit = multiplier (power of 10).

EIA-96 Code (±1%)

Two digits = value code, letter = multiplier. Used for high-precision resistors.
