(1) Inductance is measured with a LCR meter 4284A (Agilent
Technologies) or equivalent.
Test frequency at 100kHz
(2) DC resistance is measured with a Digital Multimeter TR6871
(Advantest) or equivalent.
(3) Maximum allowable DC current is that which causes a 30%
inductance reduction from the initial value, or 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
100kHz下测试电感值。
(2)通过数码万用表TR6871Advantest)或者相类似的工具测试直流
电阻。
(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)。
