FAQ
What is the value of a 473 capacitor?
47 nF (0.047 µF): 47 × 10^3 pF = 47,000 pF.
What does 473J, 473K or 473M mean?
The letter is the tolerance: J = ±5%, K = ±10%, M = ±20%. The value is still 47 nF.
Can I replace a 473 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.
