3. Ratings
Item
Rated Value
Explanation
0.031 W / element
When used at ambient temperature over 70
°C,
the rated dissipation should be reduced as shown
in Fig.1
Rated Dissipation
Chip jumper : Rated current 1 A (Resistance is less than 50 m
)
Rated voltage
&
Rated Continuous
Working Voltage
(RCWV)
The rated voltage of each resistor should be calculated from the
equation below, and when the rated voltage exceeds the limiting
element voltage, the limiting element voltage should the maximum
working voltage.
E = P
× R
Limiting element voltage : 50 V
