(1) Inductance is measured with a LCR meter 4284A(Agilent

Technologies) or equivalent. Test frequency at 100kHz

(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

(4) Temperature Rise Current based upon 40°C temperature rise.

(Reference ambient temperature 20°C)

(5)Absolute maximum voltage : 50VDC
