(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 25% inductance
reduction from the initial value.
(4) Temperature rise current is that which coil temperature rises by
40°C. (Two built-in coils are connected in series, when
measuring.)
