Digits 8-9-10-11: Capacitance
The nominal capacitance is exponential: the digits 9, 10, 11 show the first 3 significative numbers of
capacitance, the digit 8 defines the exponent on 10 base to obtain the nominal capacitance in pF,
example 2330 = 0,033 µF 330 x 102 330 x 100
33000 pF = 0,033 µF
Digits 12-13: Execution
The standard execution is coded as AA, all the others are not standard.
Digit 14: Total Length of Capacitor
0 = H max 33 mm (tape H=31.5 mm)
2 = H max 46 mm (tape H=44 mm)
4 = H max 20.5 mm (tape H = 19 mm)
6 = H max 38 mm (tape H = 36 mm)
1 = H max 44 mm (tape H=42 mm)
3 = H max 58 mm (tape H=56 mm)
5 = H max 28 mm (tape H=26.5 mm)
Digit 15: Tolerance
According to IEC 1968, this code defines the tolerance on nominal capacitance of the capacitor.
J = ± 5% K = ± 10% X = Special tolerance
