(1) Inductance is measured with a LCR meter 4284A * 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 30%
inductance reduction from the initial value, or coil temperature to rise
by 40°C, whichever is smaller.
(Reference ambient temperature 20°C)
