Capacitor : Types of Capacitors

 Capacitor Color Code:  


A color code was used on polyester capacitors for many years. It is now obsolete, but of course there are many still around. The colors should be read like the resistor code.  
·         The top three color bands give the value in pF.
·         The 4th band is for tolerance.
·         The 5th band is for the voltage rating.
For example:
          i.            brown, black, orange   means 10000pF = 10nF = 0.01µF.
Note: There are no gaps between the colour bands, so 2 identical bands actually appear as a wide band.
        ii.            wide red, yellow   means 220nF = 0.22µF.
