MEASUREMENT CONDITIONʗଌఆ৚݅
(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) Rated 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)
