PCB layout, trace thickness and width, HC3 = Product code and size air flow and proximity of other heat generating components will affect temperature XXX = Inductance value in uH. rise. It is recommended that the temperature of the part not exceed 125C under R = Decimal point. If no R is present, third character = of zeros worst case conditions verified in the end application. -R suffix indicates RoHS compliant 3) Peak current for approximately 30% rolloff ( 20C) 4) Applied Volt-Time product (V-S) across the inductor. This value represents the applied V-S at 300kHz necessary to generate a core loss equal to 10% of the total losses for a 40C temperature rise.
