1) Open Circuit Inductance Test Parameters: 100kHz, 0.25 Vrms, 0.0 Adc  
Parallel: (1,2 - 4,2) Series: (1 - 4) tie (2 - 3)  
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 approximately 30% roll-off at 20°C  
4) DCR limits @ 20°C  
5) Applied Volt-Time product (V-µS) across the inductor. This value represents the  
applied V-µS at 100KHz necessary to generate a core loss equal to 10% of the  
total losses for a 40°C temperature rise.  
6) Turns Ratio (1-2):(3-4) 1:1
