MARKING

Each resistor is marked with a three-digit(WW06P ±1%;±5%) or four-digit(WW08P ±1%;±5%) code on the

protective coating to designate the nominal resistance value.

* Remark：0603 resistor value from 0.1

to 0.976

E48/E96 series use 2 significant digits followed by

letter.(Example R560 = R56 ； R402= 59Z)

** Remark：0603 resistor value from 0.047

to 0.091

use the last Two-digits followed by “M” equals “m”, means

1/1000(Example R047 = 47M ； R050= 50M)
