5. Marking
Marking Method
The nominal inductance shall be expressed
in “µH” and consist of a number of three
figures. No tolerance of inductance shall
be indicated.
0.005 to 0.082µH
The three figures express three
decimal places.
0.10 to 8.2µH
A decimal point replaced by an alphabetical
letter “R” shall be significant figures.
10 to 330µH
The first two figures are significant
figures while the last figure shall show
the number zero.
