If the resistance value is not found in the table for 0603 product, will use normal
three digits to show the value, but will add a special mark “-“ under the three
digits. Example as following:
“ 331 ＂indicates that it is 0603
±1%
330ohm product.

3.2 Derating Curve
3.3 Operating Temperature Range -55℃~+125℃;
storage condition is 5½30℃, 30½75%RH.
3.4 Rated Voltage
The rated voltage is calculated form the rated power and normal resistance by
the following formula： E=
RP
Where：E：Rated Voltage (V)
P：Rated Power (W)
R：Normal Resistance (ohm)
In case the value calculated by the formula exceed the maximum working voltage as
3.1 the maximum working voltage shall be regarded as rated
