温度上昇許容電流(3)
(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)
