(1) Inductance is measured with a LCR meter 4284A (Agilent (1) LCR4284A (Agilent)100kHz
Technologies) or equivalent.
Test frequency at 100kHz (2) 34420AAgilent3541(HIOKI)
(2) DC resistance is measured with 34420A (Agilent Technologies) or 25C
3541(HIOKI). (Reference ambient temperature 25C) (3)
(3) Maximum allowable DC current is that which causes a 30% 30%40C
inductance reduction from the initial value, or coil temperature to 20C
rise by 40C, whichever is smaller. (Reference ambient
temperature 20C)
