Colour Codes for Resistors.

To allow for identification, resistors are usually marked with coloured bands (rings).
Often refered to as colour codes, these markings are indicative of their resistance, tolerance and temperature coefficient.

The following table documents the codes.

A: first significant figure
B: second significant figure
C: third significant figure
D: multiplier (factor by which the significant figures are multiplied to yield the nominal value)
E: tolerance
F: temperature coefficient

Examples:

Resistor 12 KOhm ±5% (NFR-Fusible, NFR25H - Extra white band)
A=Brown, B=Red, D=Orange, E=Gold.

Resistor 12 KOhm ±5% (SFR-Standard film)
A=Brown, B=Red, D=Orange, E=Gold.

Resistor 2.7 MOhm ±5% (VR-Metal glazed)
A=Red, B=Violet, D=Green, E=Yellow(*).

Resistor 82 KOhm ±5% (PRO 1/2-Power Metal film)
A=Gray, B=Red, D=Orange, E=Gold.

Resistor 47 KOhm ±1% (MRS16-Metal film)
A=Yellow, B=Violet, C=Black, D=Red, E=Brown.

Resistor 390 KOhm ±1% (MRS25-Metal film)
A=Orange, B=White, C=Black, D=Orange, E=Brown, F=Red.

(*)= This appears as yellow band instead of gold on VR types.
