(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 ）。
