Explanation
When you use one at ambient temperature over
70deg.C, the load power shall be reduced as
shown in Fig.1.
Rated Continuous
Voltage (RCWV)
The rated voltage at each resistance shall be calculated from the
equation below,
Working
E＝ P × R
Resistance Tolerance
E: RCWV(V), P: Rated Power(W), R: Resistance Value(Ω)
F:+/-1%, J:+/-5%

Specifications and Explanation
1. The surface of resistor is covered with protective coating and hard to
fade, then don't have unevenness, flaw pinhole and discoloration.
2. The surface of terminal is covered by the plating. And the plating is
hard to fade, then don't have unevenness, flaw, pinhole and
discoloration.
3. The terminal is connected with resistive plate certainly.
