Explanation
When used at ambient temperature over 70 °C,
0.031 W / element the rated dissipation should be reduced as shown
in Fig.1
Chip jumper : Rated current 1 A (Resistance is less than 50 mΩ)
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
E: Rated voltage(V), P: Rated dissipation(W), R: Rated resistance(Ω))
