Colour code: Some older capacitors use a form of colour code. This type of capacitor marking is used less these days but may be seen on some older capacitors. Tolerance codes: Some capacitors have a tolerance code. The code used is actually the same as that used with resistors as it utilises the EIA scheme.

In case of Color coded capacitors, capacitor body consists of color bands and by using a capacitor color code chart we can easily identify the capacitor value. The first color is considered as the 1 st digit in color chart, the second color band is 2 nd digit, the third band is a multiplier, the 4 th band is tolerance and the fifth color band.

Having trouble determining the value of
that capacitor on your bench?
Here's a chart to help you out. The letter
after the marking often indicates the tolerance.
+/-5%(J), +/-10%(K), +/-20%(M)
Example: 101K would be 100pf, +/-10%
