FAQ
What is the value of a 223 capacitor?
22 nF (0.022 µF): 22 × 10^3 pF = 22,000 pF.
What does 223J, 223K or 223M mean?
The letter is the tolerance: J = ±5%, K = ±10%, M = ±20%. The value is still 22 nF.
Can I replace a 223 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.
