FAQ
What is the value of a 151 capacitor?
150 pF: 15 × 10^1 pF = 150 pF.
What does 151J, 151K or 151M mean?
The letter is the tolerance: J = ±5%, K = ±10%, M = ±20%. The value is still 150 pF.
Can I replace a 151 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.
