(1) Inductance is measured with a LCR meter 4284A (Agilent
Technologies) or equivalent. Test frequency at 1MHz
(2)
DC resistance is measured with 34420A (Agilent Technologies) or
3541(HIOKI). (Reference ambient temperature 20°C)
(3)
Maximum allowable DC current is that which causes a 30%
inductance reduction from
the initial value, coil temperature to rise
by 40°C whichever is smaller.
(Reference ambient temperature 20°C)
(1)LCR仪表4284A (Agilent Technologies)或者功能相同的仪器在
1MHz下测试电感值。
(2)
通过数码万用表34420A (Agilent Technologies)/ 3541(HIOKI)或者
相类似的工具测试直流电阻。(环境温度为20°C
(3)
允许最大直流电的范围是以下两者中比较小的一个:从开始值降低
30%的电感值,或者线圈温度升高40°C
(参考周围环境温度
20°C)。
