(1) Inductance is measured with a LCR meter 4284A (Agilent
Technologies) or equivalent.
Test frequency at 100kHz
(2) DC resistance is measured with 34420A (Agilent Technologies) or
3541(HIOKI). (Reference ambient temperature 25°C)
(3) Maximum allowable DC current is that which causes a 10%
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技术)或者功½相同的仪器在100kHz下测
试电感值。
(2)
通过数码万用表34420A（Agilent技术）或者3541(HIOKI)测试直
流电阻。（环境温度为25°C）
(3)
允许最大直流电的范围是以下两者中比较小的一个：引起电感值
从最初值降½10%，或者线圈温度升高40°C。
（参考周围环境温度20°C）。
