FAQ
What is the value of a 333 capacitor?
33 nF (0.033 µF): 33 × 10^3 pF = 33,000 pF.
What does 333J, 333K or 333M mean?
The letter is the tolerance: J = ±5%, K = ±10%, M = ±20%. The value is still 33 nF.
Can I replace a 333 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.
