MECHANICAL DATA
Mass per 100 units
Marking
Each resistor, except RC31, is
marked with a three digit code
(occasionally four digit) on the
protective coating to designate the
nominal resistance value.
3-DIGIT MARKING
For values up to 91
W the R is used as
a decimal point. For values of 100
W
or greater the first 2 digits are
significant, the third indicates the
number of zeros to follow.
Example
PACKAGE MARKING
The packing is marked with the
resistance value, tolerance,
catalogue number, quantity,
production period, batch number and
source code.
