测试仪器
Test equipment:Inductance\RDC---HP4263B or equivalent, Isat\Irms--- Microtest 6379 & 6220 or equivalent.
Ls
测试频率/电压
Ls Test frequency/Voltage:100kHz/500mV;
Isat:指½电感量比初始值下降约 30%的电流值,
Irms:
指½电感器表面温度上升
40℃的电流值(参考周围环境温度 20℃)
。
Isat: DC current at which the inductance drops approximate 30% from its value without current;
Irms: The DC current is inductor surface temperature to rise by 40℃ ( Reference ambient temperature 20℃).
