Decode 6-Band Resistors

Read precision resistors that also specify a temperature coefficient.

Tolerance

💡 Read bands from the end with the tolerance band (often gold or silver) on the right. 4-band resistors use two significant digits; 5- and 6-band use three for tighter precision.

6-Band tips

🌡️

The 6th band is the temperature coefficient (ppm/K) — how much resistance drifts as the part heats up.

💡

Brown (100 ppm/K) and red (50 ppm/K) are the most common 6th bands.

🎯

Temperature coefficient matters for precision analog circuits, less so for general hobby use.
