(1) Inductance is measured with a LCR meter 4284A * or equivalent.  
(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.
