(1) Inductance is measured with a LCR meter 4284A (Agilent
Technologies) or equivalent.
Test frequency at 100kHz
(2) DC Resistance is measured with a Digital Multimeter TR6871
(ADVANTEST) or equivalent.
(3) Inductance decrease current based upon 10% inductance
reduction from the initial value.
(4) Temperature rise current based upon 40°C temperature rise.
(Reference ambient temperature 20°C)
