1) Test Parameters: 300kHz, 0.25 Vrms
2) DC current for approximately ∆T of 40°C without core loss De-rating is necessary for AC currents. PCB layout, trace thickness and width,air flow and proximity of other heat generating components will affect temperature rise. It is recommended that the temperature of the part not exceed 125°C under worst case conditions verified in the end application.
3) Peak current for approximately 30% rolloff (@20°C)
4) Applied Volt-Time product (V-µS) across the inductor. This value represents the applied V-µS at 300kHz necessary to generate a core loss equal to 10% of the total losses for a 40°C temperature rise.
Part number definition:
HC3-XXX-R
HC3 = Product code and size
XXX = Inductance value in uH.
R = Decimal point. If no R is present, third character = #of zeros
-R suffix indicates RoHS compliant
