电阻器设计所确定的,通常在电阻器上标出的阻直。
Resistance value for which the resistor has been designed, and which is generally used for denomination of the resis- tor. 用标称阻直和额定功耗乘积的平方根计算出来的直流电压或 交流电压有效直。 D.C. or A.C. r.m.s. voltage calculated from the square root of the product of the rated resistance and the rated dissi- pation. 两个规定温度之间的阻直相对变化除以产生这个变化的温度 之差。 Relative variation of resistance between two given tempera- tures divided by the difference in the temperature producing it. 相对于基准温度20℃,在类别温度之间规定的温度范围内产 生的阻直最大可逆变化。 Relative to the reference temperature 20℃, within the spec- ified temperature range between the category temperature resistance maximum reversible change.
对于电阻器的预定用途来说,降低了其使用性可看得见的损 伤。
Damage, perceptible with suitable magnification, which is likely to affect the usability of the component for its intended purpose. 对电阻器施加规定的过负荷时,阻直显著增大;使流过电阻 器的电流下降到最初试验电流的 /50以下时称为熔断。电阻 器从加上规定的过负荷时到发生熔断时所需的时间称为熔断 时间。这种性能称为熔断特性。 When applied overload , the resistor’s resistance is signifi- cantly increased, and the current through the resistor drops below /50 of the initial test current; The time from being applied overload to resistor fusing is fusing time, and this performance is called fusing characteristics.
