1、Inductance is measured with a LCR meter:HP4284A & 3532-50 or equivalent.
2、D.C .R is measured with a Digital Multimeter TH2512B or equivalent.
3、The Isat1 is the current at which the inductance decreases by 10% from the initial value
4、The Isat2 is the current at which the inductance decreases by 35% from the initial value
5、The Irms by Stand-Type is the current at which the temperature rise is △T≤40℃，whichever（Ta=20℃）
