1) Test Parameters: 100KHz, 1.0Vrms  
It is recommended that the temperature of the part not exceed 155°C under worst  
case operating conditions verified in the end application.  
2) Irms Amperes for approximately ∆T of 40°C above 85°C ambient  
3) Isat Amperes Peak for approximately 15% rolloff (@20°C)  
4) Isat Amperes Peak for approximately 30% rolloff (@20°C)  
Part number definition:  
5) Applied Volt-Time product (V-µS) across the inductor. This value represents the  
applied V-µS at operating frequency necessary to generate additional core loss  
which contributes to the 40°C temperature rise. De-rating of the Irms is required  
to prevent excessive temperature rise. The 100% V-uS rating is equivalent to a  
ripple current Ip-p of 20% of Isat (30% rolloff option).  
First 3 characters = Product code and size.  
Last 3 characters = Inductance in µH. R = decimal point.  
If no R is present third character = # of zeros.
