(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 25°C)
(3) Inductance Decrease Current based upon 20% inductance
reduction from the initial value
