Yours mate - I've not opened mine (yet). 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). Alternatively the value may be marked directly, for example 2n2 is 2.2 Nanofarads (nF).
