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 that 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. For those products whose inductance
values are specified using three designated digits, these values may
be indicated using the closest two digits instead.
