Then the 4 1 st digit, the 7 2 nd digit, the 3 is the multiplier in picofarads, pf and the letter j is the tolerance and this translates to. On potentiometers you may have other numbers besides the source and date codes. They are also used in filter circuits because capacitors easily pass ac changing signals but they block dc constant signals. Capacitor colour codes and colour code descriptions.
Direct value marking some manufacturers mark the capacitance value directly on the case, along with other information. Therefore, the total capacitance will be lower than the capacitance of any single capacitor in the circuit.
