4-1 Specification

Power Rating*

1/2 W

Resistance Range

10~50(m

Ω)

Temperature Coefficient of Resistance

±100ppm/℃

Resistance Tolerance

±1% , ±2% , ±5%

Note*:

Power rating is based on continuous full load operation at rated ambient temperature of 70℃.

For resistors operated at ambient temperature in excess of 70℃, the maximum load shall be

derated in accordance with the following curve.
