Resistor Color Code Chart and Calculator
Pick the band colours to read a resistor, or look up any colour, multiplier, tolerance and temperature coefficient in the chart. The tables follow IEC 60062:2016, and the E-series values follow IEC 60063.

Colour bands, multipliers, tolerance and tempco, E-series values, SMD and capacitor codes. These are the same tables as the printable PDF. For: Electronics students, makers, technicians and repair engineers.
- Key relationship
- Digits, then a power-of-ten multiplier, then tolerance (IEC 60062)
- Formula
- R = (digit bands as a number) × 10^(multiplier)
- Reverse
- Write the value with 2 or 3 significant digits; the exponent is the multiplier colour
- Worked example
- Yellow–violet–red–gold = 47 × 10² Ω = 4.7 kΩ ±5%
- Rounding
- Read from the end nearest a band; the tolerance band is usually set apart. Colours as IEC 60062:2016.

Resistor Color Code Chart and Calculator FAQs
Common questions about the resistor color code chart.
How do you read a 4 band resistor?
Read from the end away from the gold or silver band. Bands 1 and 2 are digits, band 3 is the power-of-ten multiplier and band 4 is the tolerance. Yellow, violet, red, gold is 47 × 100 = 4.7 kΩ ±5%.
What is the difference between a 4 band and a 5 band resistor?
A 5 band resistor has three digit bands instead of two, so it can show values from the E96 series used for 1% and tighter parts. The fourth band is the multiplier and the fifth is the tolerance; a sixth band, if present, is the temperature coefficient.
What does the code 103 mean on an SMD resistor or capacitor?
The first two digits are the value and the third is the number of zeros: 103 is 10 × 10³, so 10 kΩ on a resistor or 10,000 pF (10 nF) on a capacitor.
