FAQ
What is the value of a 472 capacitor?
4.7 nF (0.0047 µF): 47 × 10^2 pF = 4,700 pF.
What does 472J, 472K or 472M mean?
The letter is the tolerance: J = ±5%, K = ±10%, M = ±20%. The value is still 4.7 nF.
Can I replace a 472 capacitor with a different type?
Usually, if the capacitance, voltage rating and temperature characteristic are at least as good. Check the rated voltage, and remember ceramic capacitors lose capacitance at high DC voltage.
