COLOUR CODES FOR Resistors and Capacitors
1. RESISTORS Resistor Codes Resistor Coding
On the older carbon composition and carbon film resistors usually only 3 colours are used in the sequence Body - Tip and Spot .
Additional bands are for tolerance silver for +10% and gold for +5%.
A pink band indicates a high-stability component.
Resistor Colour Codes are simple for the 3-colour system but not so memorable when one has 6 bands see below!
And here, below, is the RS data sheet which extends some of the 4th, 5th and 6th band values.
2. CAPACITORS - Capacitor codes, Capacitor Coding.
The same colours apply, with the 5th band being working voltage.
The chart below shows how this is applied to the "tropical fish" capacitors.
