(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.
(Reference ambient temperature 25°C)
(5) Absolute maximum voltage 30VDC.
