(1) Open Circuit Inductance test parameters: 100kHz, 0.25V, 0.0Adc,  
tolerance is 20%  
(2) Irms: DC current for an approximate T of 40°C without core loss. Derating is  
necessary for AC currents. PCB layout, trace thickness and width, air-flow, and  
proximity of other heat generating components will affect the temperature rise. It  
is recommended that the temperature of the part not exceed 165°C under worst  
case operating conditions verified in the end application.  
(5) DCR limits @ 25°C  
(6) K-factor: Used to determine B p-p for core loss (see graph).  
B p-p = K*L*I, B p-p(mT), K: (K factor from table), L: (Inductance in µH),  
I (Peak to peak ripple current in Amps).  
(7) Part Number Definition: DRAxxx-xxx-R  
DRAxxx = Product code and size; -xxx = Inductance value in uH;  
R = decimal point; If no R is present, third character = # of zeros.  
-R suffix = RoHS compliant  
(3) Isat Amperes peak for approximately 30% rolloff (@25°C)  
(4) Isat Amperes peak for approximately 40% rolloff (@125°C)
