Resistor color code calculator
Position the resistor with the tolerance band (gold/silver) on the right, then read from left to right.
E12, E24 series: 10, 12, 15, 18, 22, 27, 33, 39, 47, 56, 68, 82 are commonly used values.
A tool that automatically calculates resistance value, tolerance, and temperature coefficient by selecting the color codes of a resistor. Supports 4-band, 5-band, and 6-band resistors with visual representation of the actual resistor appearance.
