About
Pick the colors on a 4-band, 5-band, or 6-band resistor and see its resistance, tolerance, and temperature coefficient. Or type a target value and see which color bands you need.
How to use
- Pick band count (4, 5, or 6).
- Click each color in order.
- Read the resistance value.
FAQ
What's the difference between 4 and 5 band?+
4-band: two significant digits, multiplier, tolerance. 5-band: three significant digits (more precise). 6-band adds a temperature coefficient.
