Colour Values for Resistors and Capacitor Codes

1^st Color Band: First Significant Figure

2^nd Color Band: Second Significant Figure

3^rd Color Band: Decimal Multiplier

4^th Color Band: Tolerance

eg. Resistor color reads: Brown, Black, Red, Silver

1st Significant Figure : 1

2’nd Significant figure : 0

Multiplier: 10²

Tolerance: 10%

For a resistor value of 1000 ohms with a tolerance of 10%.  

Tolerance color other than gold and silver for capacitors only.

Capacitor Codes

Mica Capacitors

The first dot on a mica capacitor is White to indicate EIA six dot code. It may also be Black for military code. In either case, read the capacitance in picofarads from the next three color dots. The fifth dot will indicate the tolerance. (See chart above for tolerance color codes.) The sixth dot indicates classes A to E of leakage and temperature coefficients,. The maximum rating for DC working voltage is generally 500 V.
