6Inductance
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.
