(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 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½30%，或者线圈温度升高40°C。

（参考周围环境温度20°C）。
