What do the letters on a capacitor mean?
Letters that follow the number codes (ex: 103J or 252M) are the
tolerance, or how much a capacitor may deviate from its official
value. Common values are shown below:E +/- 0.5% F +/- 1%G +/- 2% H
+/- 3%J +/- 5% K +/- 10%M +/- 20% N +/- 30%P +100% ,-0% Z +80%,
-20%
Different classes of capacitors have different meanings for
their letter codes. You can find a very good listing of all
capacitor codes at TransTronics and more on ceramic codes at
wikipedia.
