(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) Maximum allowable DC current is that which causes a 30%
inductance reduction from the initial value, coil temperature to rise
by 40°C, whichever is smaller.
