Frequently asked questions
What is a 474 capacitor?
A capacitor marked 474 is 470 nF: 47 followed by 4 zeros in picofarads, 470,000 pF, which is also 0.47 µF.
What is 474 in µF and nF?
474 = 470,000 pF = 470 nF = 0.47 µF.
What do 474J, 474K and 474M mean?
The same capacitance, 470 nF, with a tolerance of ± 5 % (J), ± 10 % (K) or ± 20 % (M).
