(1)Inductance is measured with a LCR meter 4284A (Agilent
Technologies) or equivalent.
(1) LCR仪表4284A(Agilent技术)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34420A(Agilent技术)或者3541(HIOKI)测试直
流电阻。(环境温度为25°C)
(3) 电感值降低电流是基于电感值从最初的值降低30%计算的。
(4) 温度升高电流是基于温度上升40°C的基础上衡量的。(参考周
围环境温度25°C)
Test frequency at 100kHz
(2)DC resistance is measured with 34420A (Agilent Technologies) or
3541(HIOKI). (Reference ambient temperature 25°C)
(3)Inductance Decrease Current based upon 30% inductance
reduction from the initial value
(4)Temperature Rise Current based upon 40°C temperature rise.
