(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 40ˆ, whichever is smaller.
(Reference ambient temperature 20ˆ)
