(1) Inductance is measured with a LCR meter 4284A (Agilent
Technologies) or equivalent.
Test frequency at 100kHz
(2) DC resistance is measured with 34420A (Agilent Technologies) or
3541(HIOKI). (Reference ambient temperature 25°C)
(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)
