(1) Open Circuit Inductance Test Parameters: 100KHz, 0.25Vrms, 0.0Adc.  
(2) RMS current for an approximate T of 40°C without core loss. It is  
recommended that the temperature of the part not exceed 125°C.  
(3) Peak current for approximate 30% roll off at 20°C.  
(4) DCR limits @ 20°C.  
(5) Applied Volt-Time product (V-µS) across the inductor. This value represent the  
applied V-µS at 100KHz necessary to generate a core loss equal to 10% of the  
total losses for 40°C temperature rise.
