(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) Maximum allowable DC current is that which causes a 10%
inductance reduction from the initial value, or coil temperature to
rise by 40°C, whichever is smaller.(Reference ambient
temperature: 20°C)
