Tool to find the value of a capacitor. The Capacitor color code is similar to that of resistors and therefore applies partly to capacitors and provides a visual value.

A capacitor is an electronic component capable of temporarily storing an electrical charge before discharging it.

A capacitor is characterized by its capacitance expressed in farads (F).

The capacitors use a capacitor color code similar to the resistors color code (3, 4 or 5 bands).

The first two colors indicate significant digits of the value of the capacity (in pF), the next colour is the corresponding power of 10, the other two colors are optional and indicate tolerance and maximum voltage.

Black | 0 |

Brown | 1 |

Red | 2 |

Orange | 3 |

Yellow | 4 |

Green | 5 |

Blue | 6 |

Violet | 7 |

Grey | 8 |

White | 9 |

Gold | -1 |

Silver | -2 |

__Example:__ A capacitor [Red, Blue, Orange, Green] has corresponding values for colors Red = 2, Blue = 6, Orange = 3, Green = 5

Make the calculation $$ ( [Color1] \times 10 + [Color2] ) * 10 ^ {[Color3]} ± [Color4]\% (Tolerance) $$

__Example:__ 26 x10^3 ± 5% = 26000 pF ± 5% = 26 nF ± 5%

The capacitors have capacities expressed in Farad. In practice sub-multiples are used:

1 F = 1000 mF (milli Farad)

1 mF = 1000 µF ou uF (micro Farad)

1 µF = 1000 nF (nano Farad)

1 nF = 1000 pF (pico Farad)

Sometimes the capacitor value is indicated with 3 digits. As for colors, the first 2 are significant digits, and the third is the power of 10.

__Example:__ 123 => 12 x10^3 => 12 nF
