Flg.1
Explanation
When used at ambient temperture over
0.125 W
70°C, the load power should be reduced
(at 70 °C or lower)
as shown in Fig.1
The rated voltage of each resistance should be calculated from the
equation below, and when the rated voltage exceeds the
½imiting
element voltage, the
½imiting
element voltage should be the rated
voltage.

5. Appearance & Construction
Item
Rated value
Explanation
1. The resistive element should be covered with protective coating
that don’t fade easily. The surface of coating should avoid
unevenness, flaw, pinhole and discoloration.
Appearance &
2. The electrode should be printed uniformly, as shown in the
Construction
dimensions. The plating should not fade easily, and should avoid
unevenness, flaw, pinhole, projection and discoloration.
3. The electrode should be connected electrically, mechanically to
resistive element.
As far as there shall not designation especially, the following test and measurement
shall be operated under normal temperature (5~35°C), normal humidity(45~85%),
