Frequently Asked Questions
4 vs 5 vs 6 band
4-band: 2 digits + multiplier + tolerance. 5-band: 3 digits + multiplier + tolerance (precision). 6-band: 5-band + temperature coefficient.
Reading direction
Tolerance band (gold/silver) goes on the right. If unclear: gaps between groups, wider band closer to leads is usually the tolerance.
