The capacitance value is often marked using a 3 digit code. This works in the same way as resistor coding but using numbers instead of colours. The first 2 numbers give the value and the last number is the multiplier. These give the value in Picofarads (pF), e.g. code 103 = 1 0 000pF (=0.01uF - see Capacitance Conversion Table). Alternatively the value may be marked directly, for example 2n2 is 2.2 Nanofarads (nF).
A single letter is often used to indicate the tolerance of the component. These can be translated using the following table:
|Z||- 20% +80%|
The dielectric material is often marked in abbreviated form. The table below shows the meaning of these abbreviations.
|MKT||Metallised Polyester (PETP)|
|KT||Polyester Film / Foil|
|KS||Polystyrene Film / Foil|
|KP||Polypropylene Film / Foil|
