(1) Inductance is measured with a LCR meter 4284A (Agilent  
Technologies) or equivalent.  
(2) DC resistance is measured with 34420A (Agilent Technologies) or  
3541(HIOKI). (environment temp. of 25°C)  
(3) Inductance Decrease Current based upon 20% inductance reduction  
from the initial value.  
(4) Temperature Rise Current based upon 40°C temperature rise.
