yInductance
Expressed by three-digit alphanumerics. The unit is micro-henry
(µH). The first and second figures are significant digits, and the
third figure expresses the number of zeros which follow the two
figures. If there is a decimal point, it is expressed by the capital
letter "R". In this case, all figures are significant digits. If
inductance is less than 0.1µH, the inductance code is expressed
by a combination of two figures and the capital letter "N", and the
unit of inductance is nano-henry (nH).
The capital letter "N" indicates the unit of "nH", and also
expresses a decimal point. In this case, all figures are significant
digits.
