First, read the English article below.

Older capacitors are less predictable, but almost all modern examples use the EIA standard code when the capacitor is too small to write out the capacitance in full. To start, write down the first two digits, then decide what to do next based on your code:  If your code starts with exactly two digits followed by a letter (e.g. 44M), the first two digits are the full capacitance code. Skip down to finding units. If one of the first two characters is a letter, skip down to letter systems. If the first three characters are all numbers, continue to the next step. The three-digit capacitance code works as follows:  If the third digit is 0 through 6, add that many zeroes to the end of the number. (For example, 453 → 45 x 103 → 45,000.) If the third digit is 8, multiply by 0.01. (e.g. 278 → 27 x 0.01 → 0.27) If the third digit is 9, multiply by 0.1. (e.g. 309 → 30 x 0.1 → 3.0) . The smallest capacitors (made from ceramic, film, or tantalum) use units of picofarads (pF), equal to 10-12 farads. Larger capacitors (the cylindrical aluminum electrolyte type or the double-layer type) use units of microfarads (uF or µF), equal to 10-6 farads. A capacitor may overrule this by adding a unit after it (p for picofarad, n for nanofarad, or u for microfarad). However, if there is only one letter after the code, this is usually the tolerance code, not the unit. (P and N are uncommon tolerance codes, but they do exist.) Ceramic capacitors, which are usually tiny "pancakes" with two pins, typically list the tolerance value as one letter immediately after the three-digit capacitance value. This letter represents the tolerance of the capacitor, meaning how close the actual value of the capacitor can be expected to be to the indicated value of the capacitor. If precision is important in your circuit, translate this code as follows:     B = ± 0.1 pF. C = ± 0.25 pF. D = ± 0.5 pF  for capacitors rated below 10 pF, or ± 0.5% for capacitors above 10 pF. F = ± 1 pF or ± 1% (same system as D above). G = ± 2 pF or ± 2% (see above). J = ± 5%....
