额定电流
额定电流计算方式如下
(The rated current is calculated by the following formula):
I=
P/R
I:额定电流(Rated current)(A)
P:额定功率(Rated Power)(W)
R:额定电阻(Resistance)(ohm)
如果计算出的电流超过此型别的最大工作电流,则此型别的最大工作
工作温度范围(Operating Temperature Range):-55℃~+170℃。
当电阻在高于 70℃的周围环境中工作时,最大负载功率应该按照以
电流为此电阻的额定电流
(In case the value calculated by the formula exceed the
maximum working current as above table, the maximum
上曲线减少。
working current shall be regarded as rated current.)
When the resistor is operating in an ambient environment
above 70 °C, the maximum load power should be reduced
according to the above curve.
