FAQ
What is the value of a 334 capacitor?
330 nF (0.33 µF): 33 × 10^4 pF = 330,000 pF.
What does 334J, 334K or 334M mean?
The letter is the tolerance: J = ±5%, K = ±10%, M = ±20%. The value is still 330 nF.
Can I replace a 334 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.
